A Study on Fatigue and Fracture Toughness on Change Temperature of Spring Steel for Automobile
자동차용 스프링강의 온도변화에 따른 피로 및 파괴인성에 관한 연구
Abstract
Recently, the steel parts used for automobiles and trains are required to be used under higher stress than ever before in need of the weight down. In this study, high strength and superior toughness spring steels as the suspension material, used for automobile and railroad industries were utilized to carry out the following in vestigations; 1) To evaluate the characteristics of fatigue crack propagation, the experiments of fatigue crack growth were respectively carried out at the room temperature(RT),
