A Behavior of Fatigue Crack Growth of Nonmagnetic Steel with Large Grain Size
조대조직을 갖는 비자성강의 피로균열진전거동
Abstract
High manganese steel was maintained stability of Non-Magnetics performance. Fatigue tests were carried out under constant stress amplitude, using a non-magnetic high manganese steel. The fatigue crack growth mechanism of the high manganese steel was clarified from results such as observation of crack growth path and fracture surface. The result of getting this study was shown as following: 1) Remarkably
