Lecture Notes: The Heat Treatment of Steel

 · The term annealing includes the called normalizing. Parts to be normalized may be heated to a slightly higher temperature than in full annealing. This produces a coarser grain structure, which is more easily machined if the material is a low-carbon steel. In the normalizing the part is cooled in still air at room temperature

Nitriding

Nitriding is a heat treating that diffuses nitrogen into the surface of a metal to create a case-hardened surface. These processes are most commonly used on high-carbon, low-alloy steels. They are also used on medium and high-carbon steels, titanium, aluminium and molybdenum.In 2015, nitriding was used to generate unique duplex microstructure Martensite-Austenite, Austenite-ferrite
