Concept explainers
Whether a part is forged or cast and the features should be investigated to arrive at a conclusion.
Explanation of Solution
In manufacturing industries, the forging is one of the oldest manufacturing processes. It is a process in which material is converted into the finished product through heating, cooling, and hammering process. Some forging process are cold forging, die forging, and warm forging.
Casting is also one of the oldest manufacturing processes in which the molten raw material is shaped into a desired finished product with the use of molds. Some types of casting process are sand casting, die casting, centrifugal casting, and many more. Similar parts are prepared by forging process and casting process.
Some parameters such as temperature, toughness, tensile strength, hardness, microstructure, and many more are used to found whether the part is forged or cast. The cast and forged parts have different temperatures. The tensile test is done to investigate the toughness of the part because the forged part has higher toughness. In forging, there is plastic deformation take place; hence the forged parts are smaller grain size compared to the casting process. The main investigation is roughness and characteristics of the surface. The forged product is nearly always heavier compared to the cast product.
