Correlation between Magnetic Memory Signals and Mechanical Properties of 35CrMo Tempered and Quenched Steel

摘要：

　　Magnetic memory signals and hardness of 35CrMo tempered and quenched steel were acquired during tensile testing.The magnetic signals of 35CrMo steel increased monotonously with the increase of tensile stress before yielding, followed by sudden decrease with further increase of stress after yielding.The zero-cross point of Hp(y) varied during tensile testing, indicating varied position of stress concentration zones with the process of tensile testing.The Vickers hardness of the stress concentration zones of 35CrMo steel was lower than that around it, which may be attributed to the residual stress.The relationship between zero-cross point of Hp(y) and Vickers hardness was considered.
