Hot working is a manufacturing process that involves shaping materials, typically metals, at elevated temperatures. This technique makes the material more malleable, allowing it to be easily formed into desired shapes without cracking. Common methods of hot working include forging, rolling, and extrusion. During hot working, the temperature of the material is kept above its recrystallization point, which helps to refine its grain structure and improve its mechanical properties. This process is often used in industries such as aerospace, automotive, and construction to create strong, durable components that can withstand high stress and strain.
