Heat Treatment And Qualitative Metallographic Analysis Lab Report

This lab was conducted in order to determine the melting points of five samples: pure urea, pure trans-cinnamic acid, 90% Urea and 10% trans-cinnamic acid, 50% Urea and 50% trans-cinnamic acid, and 10% Urea and 90% trans-cinnamic acid. The melting points of the substances listed above were obtained by placing 1-2mm samples of each substance in a Mel Temp. From the obtained melting points, a binary phase diagram was created.

In a similar manner to specimen 1, the forged product is undergone a full annealing P2 at a temperature of 530° C approx for 3 hours. Such full annealing can improve the mechanical process ability of the

Welding must be done carefully to avoid contamination and machining must be done precisely. Titanium is very reactive to atmospheric gases and can result in degradation in the material. Titanium is weldable in annealing conditions but provide limited weld ductility and heat affected zone ductility. It can also be significantly strengthened by cold working.

The optimal grinding parameters for AISI 316 Stainless steel are predicted based on simulated annealing algorithm using MAT lab. The developed empirical models, Equation 3, 4 and 5 are used as the fitness functions for determining the material removal rate, roundness and surface roughness value of each new point. The optimization was run for several iterations and terminated when there was no change in fitness function. The simulation results are shown in Fig. 3. The optimal grinding parameters for maximum material removal rate, minimum roundness, minimum surface roughness and minimum COF are predicted and presented in the Table 5. The optimal grinding parameters obtained for maximum material removal rate result in very high roundness which

Overall, the 1018 and 1045 steel specimens displayed similar relationships between the heat-treating procedures. The 1045 steel had a greater tensile strength in all states except for the quenched state. In general, the 1018 steel specimens were more ductile than the 1045 steel specimens in all states.

The metals were placed into a clay crucible and then heated at a very high temperature inside a kiln containing a charcoal fire. Following the implementation of copper extraction, it was discovered that the process of combing metals gave them superiorities like strength, in bronze.

The main purpose in doing this experiment was to figure out how much of the percentage of Copper’s mass is in a brass alloy using a spectrophotometer that is hooked up to the laptop. Another purpose in doing this experiment is to learn how to use the Beer’s Law plots to learn how to use the equation and get the correct concentrations. This is important in everyday context because it is important for people who work doing many different types of jobs. Safety Information: In this lab, we used nitric acid to reactant with copper.

Steel is a common alloy made up mainly of iron, along with various other elements. Because of steel’s amazing strength that can withstand high pressure and temperatures, it has many different uses in the construction business (Mukherjee). Alloyed steel is used for the bodies and framework of many buildings such as skyscrapers and other things including bridges, machinery, large carrier ships, and various auto parts for vehicles. (Mukherjee) Steel is not only used in construction, but also in manufacturing. Stainless steel is extensively used to make assorted kitchen cookware, cutlery, and other appliances (Mukherjee). Other forms of iron that are commonly used in manufacturing are cast and wrought iron. According to many people, cast iron is a practically indispensable part of any normal kitchen. Its uniform heating quality makes it a great choice for manufacturing skillets, which is its most common use (Mukherjee). Along with cast iron, wrought iron is a commonly used metal in manufacturing. Wrought iron fences, trellises, arbors, and patio furniture are examples of common items found in the outdoors of average households (Mukherjee). This research will

In this experiment eight samples of 8620 steel were tested using heat treating, quenching, and tempering. One sample was normalized by heat treating, one was annealed by heat treating and oven cooling, one sample was water quenched, and the final five samples were oil quenched. Four of the oil quenched samples were tempered at the following temperatures: 1000°F, 1100°F, 1200°F, and 1300°F. Each sample underwent Rockwell Hardness testing and three Izod Impact Toughness Tests and the averaged results are shown in Figure 1

The surface coating field is a rapidly developing area of science and technology that offers new methods and techniques to control friction and wear. New coating types are continually being developed and the potential applications in different industries are ever growing, ranging from machine parts and consumer products to medical instruments and prostheses. stainless steel fades when exposed to the environment. Modern technology increasing stresses on the material. Both the uses and the stresses have grown at a maximum rate than the number of materials that can be used to meet them. Although lot of work is done by producing new alloys with improved properties, there is a limit to the protection that can be afforded by this means alone. For this reason coatings have played an important role in protecting the structural metals from environmental attack.

Steel products were defined by several attributes which determined the product application and defined quality. Grade described the metallic (chemical) composition of the steel, or the elements added to the basic recipe of iron and carbon to create the desired properties. Product described the shape of the product, including semi-finished shapes (blooms, billets and bars) and finished shapes (wires and coils). Surface finish described the smoothness and polish that could be applied to the material’s surface to enhance presentation. Size described the latitudinal and longitudinal dimensions of the product. Structural quality described the absence of breaks in the inner metallic structure. Surface quality described the absence of cracks or seams on the surface. Because specific applications called for specific attributes, many products were customized along one or more attributes for the customer. However, of all attributes, customers valued most the grade, which determined product performance.

The Tensile tests were carried out on the fabricated welds according to the standard given by the ASTM E8M- 04, the welded plates are marked for the right dimensions and sheared manually to a width of 100mm. Generally two tensile pieces are cut from each welded joints piece for accuracy. The specimens are noticeable for identification, the centre of the weld is identified and 40 mm mark is made to facilitate the measurement of elongation after the test sample breaks under tension the specimens at the marking

I got admitted at the University Of Tehran, one of the best universities in Iran. Then, I decided to perform my master’s thesis on “mechanical properties of materials after performing metal forming processes” under the supervision of Professor K. Abrinia. My studies made me familiar with ultra-fine grain materials produced by equal channel angular extrusion (ECAE). Moreover, I audited Dr. Soltani’s “fracture mechanics” class which in turn greatly contributed to the idea of improving the fatigue behavior of ultra-fine grain materials produced by ECAE as my M.Sc. thesis.

In recognition of this problem, the School of Mechanical, Material and Mechatronics Engineering at the University of Wollongong has set a developed high temperature steel testing experiment, and already made recommendations which will be a starting point for future research about various factors affecting the oxidation process. This document represents the test conducted on steel in hot rolling particularly steel grade AISI 445. We describe our preliminary findings regarding the oxidation of stainless in hot rolling and make specific recommendations for procedures that will lead to an improved experience.
