Research Abstract

Creep is one of the failure mode of high temperature equipment. Residual life is estimated by statistic analysis using feature of creep void that is small vacancy. Previously, the two dimensional analysis for void is used. In this research, method for measurement of three-dimensional geometry of void is developed by combining 3D-EBSD method and SEM images. The method enabled three-dimensional analysis of void. The method is applied to Chrome Molybdenum Steel that has been creep damaged. In the results, the void volume ratio, the variation of geometry by time and the relationship between grain boundary with void and stress direction are clarified.
