Microstructure and Mechanical Properties of Low-Si Spring Steels Produced by Quenching- Isothermal-Quenching-Tempering Process

Abstract:

An investigation of low Si spring steels (50CrVA) subjected to quenching-isothermal-quenching-tempering (Q-I-Q-T) process is presented. The results indicated that Q-I-Q-T process lead to the excellent mechanical properties compare to those treated by traditional heat-treatment, quenching and tempering, owing to the multiphase structure. The Q-I-Q-T treated microstructure consists of martensite, retained austensite, bainite and fine distributed carbides.
