| Abstract: | The refining process and heat treatment on torsion fatigue and the fracture characteristics ofone-way torsion fatigue of steel 50CrVA were studied. The tested results show that the fatigue life of steel50CrVA increased with refining and quenching-tempering or normalizing as pre-heat treatment. |
