概要
We investigated the magnetic properties, hardness and microstructure of the martensitic stainless steel with and without quench. The quench introduced to fine grain boundaries, which relates to an increment of coercivity and Vickers hardness, a decrease in Barkhusen signal. The magnetic property changes reflect the changes in microstructures and mechanical property appeared on the quenches specimen. The obtained results contribute to aim developing a magnetic nondestructive evaluation of residual stress appeared on the steel combined with and without quench.
