WebThis course is designed to familiarize vocational students with construction in sheet metal layout. The document outlines goals, specific block objectives, layout practices, blueprint reading, sheet metal forming (by hand and by machine), and heat treatment of metals, and includes posttest samples. Although ferrous metals account for the majority of heat-treated materials, alloys of copper, magnesium, aluminium, nickel, brass, and titanium may also be heat treated. About 80% of heat treated metals are different grades of steel. Ferrous metals that can be heat treated include cast iron, stainless steel and various … See more There are various reasons for carrying out heat treatment. Some procedures make the metal soft, while others increase hardness. They may also affect the electrical and heat … See more In simple terms, heat treatment is the process of heating the metal, holding it at that temperature, and then cooling it back. During the process, the metal part will undergo changes in … See more There are quite a few heat treatment techniques to choose from. Every one of them brings along certain qualities.
