The heat treatment report contained within these pages is the result of a lab practical where two samples, ‘as is’ and ‘quenched’, are tested for hardness using the Vickers method. The data obtained from these samples was, ‘as is’ HV204.9 and ‘quenched’ 472.0’. This quantified data has been analysed and discussed. Comparisons of this data have been made, and have led to a conclusion, that is clearly visible with scrutinising. This conclusion shows us that the hardening of a suitably high in carbon steel by the method of quenching is an extremely efficient method. Further testing would be recommended.

Please refer to the class handout attached as ‘Appendix 1’.

The results of this Lab Practical on heat treatment provides an informative and clear result. The two samples tested, ‘as is’ and ‘quenched’, and the data obtained from the testing of these two samples, clearly demonstrate the differences between a heat treated object and a non-heat treated object.
This data will be used to make two comparisons:
Firstly, the results from the Vickers Hardness Test will be looked at and a comparison made. By looking at ‘table 1’ and ‘graph 1’, this allows us to see that the ‘quenched’ sample has a higher reading in HV of 267.1, compared to the ‘as is’ sample.

Process Heat Treatment

...1. The type of heat performed on the steel is called annealing which involves the heating of a metal to a suitable temperature for a certain time called “ soaking “, and gradually cooling. The soaking time is calculated using this formula: Soaking Time = (1Hr)(tmax) Where tmax is the maximum thickness (in inches) of the steel. And our tmax for this experiment = 0.372in as shown in Table 3. Therefore, Soaking time = (1hr)(0.372") = 0.372hr = 22.32minutes Shorter soaking times can be used during an annealing heat treatment if an increase in material hardness and less ductility is desired. 2. The micrometer was used to measure the cross-sectional dimensions of the steel before and after the heat treatment and values where recorded as shown in Table 3. And it was observed that there was an increase in the workpiece (steel) size after the heat treatment when compared with the dimensions before the heat treatment as shown in Table 3, this simply means that there was an increase in ductility after the heat treatment was performed. 3. In terms of mechanical properties after this heat treatment, a softer material was obtained, there was an increase in ductility which improves machinability and formability. If a slightly harder workpiece is desired, the workpiece should be: * Heated to the austenite phase and then quenched with water or oil. This rapid cooling results in a hard and brittle workpiece. * The soaking time should be shorter. Table 1. The......

Plasma Nitriding Lab Report

...1. Introduction Plasma nitriding (PN) is a common low temperature thermo-chemical surface treatment that is applied to the machine parts and tools made of steels, aluminum alloys and titanium alloys to increase their reliability and performance[1,2]. In this process, a plasma is developed around the workpiece within a chamber by application of a high electric potential between anode (earth-connected chamber wall) and the cathode (the workpiece) in a low pressure N2-H2 atmosphere. N-containing ions and/or radicals are produced within the plasma. Ions accelerate to the cathode where they discharge or dissociate and resulting nitrogen atoms are introduced and diffuse into the surface. Sputtering caused by surface bombardment with ions within...

Spring Shortening

...the spring packaging, saying that in fitting this spring the muzzle energy may exceed the legal limit....! So, if this happens with your new spring, you will need to shorten it. Before we look at how to do that, perhaps we should try to understand a little more about the spring material and how it responds to the inevitable application of heat at the shortened end. Spring Steels. There are many different types of material that can be used in spring production. Each material has different compositions and properties. Steel spring material is typically 0.45 – 0.90% Carbon, with additions of Manganese, Silicon, Chromium and Vanadium. In general, the more the alloy content, the larger the diameter of wire or rod can be hardened through the entire section. Because of the small diameter wires used in manufacturing airgun springs, there is no need to add cost by using highly alloyed steel. Typically, small diameter wire coil springs will be made from “Carbon” spring steel, or “Silicon-Manganese” spring steel. The composition of the steel wire (particularly the Carbon content) makes it able to respond to heat treatment. We can make it harder or softer, by a...

Road Heaters

...The winter time is harsh for driving, snow and ice collecting on the roads making it dangerous to drive. Researchers are developing new ways to clear roads of snow and ice, without the cost of salt trucks and plows. The IHT (Interseasonal Heat Transfer) system is a road heating treatment that will melt the snow and ice off the road. The IHT is made up of water pipes underneath the road; the summer sun heats the road and pipes warming the water. The warm water is stored in a highly insulated storage tank. The warm water is pumped back into the buried pipes in the winter to melt ice and snow, and keep roads clear. The IHT system would make winter driving safer, the amount of traffic collisions would greatly decrease during the winter. The roads will automatically be ice-free making slide-offs a thing of the past. Traffic will run smoothly, without delays and detours. The public transit systems wouldn’t have to close due to hazardous road conditions. The IHT system will save on energy and fuel costs for cities. Snow plows and salt trucks cost cities a lot of money to keep running. The IHT system will help cities save money on those costs by making plows and salt obsolete. Business too would benefit from the IHT, for not having to close during bad winter weather, never having to lose revenue. Schools would not have to close causing unhappy kids from no snow days. The IHT system can increase road life. The IHT system, keeping the roads clear, will prevent road......

Investigatory Project

...Abstract The researchers’ experiment aimed to determine what material would stay and remain the same with the most heat after being heated and cooled. In this way, one could see how climate in different countries and places are being affected with the materials around them. In this experiment, the materials that were used were water, salt, oil, 2 thermometers, containers, lamp/flashlight and a stopwatch. All these materials were arranged in a way that light from the lamp could be directly reach the 2 containers; this point was where the temperature of each was being recorded with the time allotted. In order to come up with a good result, the temperature was being checked after every five minutes and placed into data. The procedure was done three times for every material for the three trials. After testing, the oil absorbed a lot of heat, the water absorbed a little heat but kept it in while the soil did not absorbed much heat but when after, it was released easily. This experiment was to show how heat was being absorbed and released by different materials around. In this manner, one could associate it with the climate; how the materials surrounding the place can affect the climate and the specific materials that would greatly affect the climate in one place. CHAPTER 1 THE PROBLEM AND ITS SCOPE Introduction Climate change is a lasting and significant change in the distribution of weather patterns over a period of time that may be ranging from decades to even......

Energy Conserving

...Household energy consumption is examined in the specific context of home heating expenditures. Analysis of home heat costs across stages of the family life cycle reveals a distinctly different pattern than previously found when total household energy costs were examined. In contrast to the curvilinear pattern where expenditures peak during middle stages of the life cycle, these data show a positive linear relationship where higher costs are associated with elderly consumers. The research focus is expanded to include heat-related conservation behavior as well as expenditures in an effort to better understand implications for policy makers and-marketers. INTRODUCTION According to reports from the Department of Energy, energy consumption in the average home could be slashed by 60% through the use of conservation methods and investment in new products to improve the efficiency of consumption. Toward this end, DOE (1980) survey results show some sort of conservation-related equipment or insulating material was added to 50% of the housing units eligible for Federal energy tax credits in 1977-78. Homeowners in 1980 claimed tax credits on an estimated $4 billion worth of investments in energy saving products primarily related to home heating. Analysts suggest that this investment rate could reach the $30 billion level per year by 1990 (Business Week 1981). As the result of consumer efforts from 1973-1980, DOE estimates that energy consumption per household has been reduced an......

Dearerator Principles

...ALTAIR EQUIPMENT CO.,INC. Water Treatment Technologies WARMINSTER, PA. 18974 DEAERATORS Why Deaeration Corrosion of iron or steel in boilers or boilers feed water piping is caused by three fundamental factors: 1. Feedwater temperature 2. Feed water ph value 3. Feedwater oxygen content Temperature and ph value influence the aggressiveness of corrosion. The higher the temperature, and the lower the pH value the increased aggressiveness of the feedwater. The dissolved oxygen content of the feedwater is a large factor in determining the amount of corrosion that will take place. The presence of oxygen, and other non-condensable gases, in the feedwater is a major cause of corrosion in the feedwater piping, boiler, and condensate handling equipment. Deaerator Principles Deaeration is the mechanical removal of dissolved gases from the boiler feedwater. There are three principles that must be met in the design of any deaerator. 1. The incoming feedwater must be heated to the full saturation temperature, corresponding to the steam pressure maintained inside the deaerator . This will lower the solubility of the dissolved gases to zero. 2. The heated feedwater must be mechanically agitated. This is accomplished in a tray deaerator by first spraying the water in a thin film into a steam atmosphere. Creating a thin film reduces the distance the gas bubble has to travel to be released from the water. Next, the water is cascaded over a bank of slotted......
