1Cr-1Mo-0.25V 강의 열화거동에 관한 연구
A Study on Degradation Behavior of 1Cr-1Mo-0.25V Steel
초록
The remaining life estimation for the aged components in power plants as well as chemical plants are very important because mechanical properties of the components are degraded with time of service exposure in the high temperature. Since it is difficult to take specimens from the operating components to evaluate mechanical properties of components, accelerated aging technique are needed to estimate and analyse the material degradation. In the this study, test materials with 4 different degradation levels were prepared by isothermal aging heat treatment at
