Microstructure and Mechanical Properties of 22MnB5 Steel with Different Cooling Method

Abstract:

Microstructure and mechanical properties of 22MnB5 Steel were analysis with different cooling method. The result show that the volume fraction of martensite in 22MnB5 is increased with the rising of cooling speed, the microstructure with air cooling is composed of ferrite and pealite, and the quenched microstructure is 100% martensite with metal die cooling and water cooling, tensile strength increased with the rising of cooling speed. The highest tensile strength is 1569.60MPa with elongation only 2.13% with water cooling method.
