Research Progress on Effects of Cooling Process on Structure and Mechanintal Properties of Typical Steel

Cooling process is a key step in steel heat treatment. After heating, the external oxide layer and internal structure of steel materials show different characteristics under different cooling conditions. The effects of different cooling rates and cooling media such as air and water on the microstructure, mechanical properties and oxide scale of steel after high temperature were summarized, so as to provide references for the influence of cooling process on typical steel.
