Notch Sensitivity after Various Methods of Thermomechanical Hardening of Steel

摘要

Minimum susceptibility to pressure concentrators is provided by high temperature mechanical treatment. During treatment at equal strength, the susceptibility to pressure concentrators after combined thermomechanical treatment is lower than after low temperature mechanical treatment. Intermediate high tempering with subsequent hardening by quenching, improves machinability by means of cutting, and decreases the susceptibility of steel, subjected to thermomechanical treatment to concentrations of pressures.
