Hot working. First, the raw material in the form of large ingots or billets is hot-worked, usually by rolling, forging, or extrusion, into smaller shapes and sizes. Historically, metalworking posses one of key domains in materials science. It is the process of working with metals to create individual parts, assemblies, or large-scale structures.
