Abstract
Four different heat treatment routes which were called step quenching were taken and accordingly different morphology dual-phase samples have been obtained. It is found that Maximum shear stress increases with martensite volume increases. They have the following relationship: Maximum shear stress = 1.14(MVF)2 – 90.7(MVF) + 24266 MPa. Adiabatic shear bands and cracks led by them are important signs during the dynamic torsional tests
