Microstructure and Mechanical Properties of 22MnB5 Steel with Different HeaTreatment

摘要：

　　Microstructure and mechanical properties of 22MnB5 Steel were analysis with different heat treatment experiment.The result show that the martensite lath with water cooling become smaller than that with metal die cooling, The lath martensitic microstructure is disappeared with die cooling & tempered specimen.The tensile strength reaches the highest 1645.34MPa by water cooling, but the plastic strength product is lowest.Q&P and die cooling & tempering process can improve the elongation of 22MnB5 with a small amount of tensile strength decrease.The plastic strength product reaches the highest of 20312.74MPa·% by die cooling & tempering method.
