Tensile Properties and Creep Rupture Characteristics of Cu-1Cr-0.5Zr/STS316L Friction Welded Joints at Elevated Temperature

Cu-1Cr-0.5Zr 합금과 STS316L강의 마찰용접재의 고온 인장 성질과 크리프 파단 특성

In this paper, the elevated temperature tensile properties and short-time creep rupture characteristics were investigated for the friction welded joints of dissimilar materials, Cu-1%Cr-0.5%Zr and STS316L. The joining tests on Cu-1%Cr-0.5%Zr/STS316L by friction welding were performed, and optimum joining conditions of the friction welded joints were determined. The characteristics of the elevated temperature tensile strength, hardness, fractographs were examined, and the creep rupture characteristics for the optimum welded joints were investigated under uniaxal static load at 300, 400 and $500^{\circ}C$.
