Single crystal Ni base superalloy has been applied to gas turbine materials for the most efficient electric power plant technology and it will be used under the conditions of high temperature and creep. In this study, mechanical tests under the conditions of high temperature creep were conducted for single crystal Ni base superalloy CMSX-4. Also, to undetstand vacancy diffusion behavior, the analysis of micro damage behavior for single crystal Ni base superalloy coupled with the vacancy diffusion behavior is earned out.
