摘要：
The high-resolution time-of-flight (TOF) diffractometer Sirius at KEK has been utilized to measure the residual strain in the unidirectionally solidified Al2O3/Y3Al5O12 composite precisely. Since the sample is a double single-crystalline composite material, we developed a new technique combining Laue patterns and high-resolution TOF data of each Laue spot, which enabled detailed indexing of the Laue pattern as well as extracting the residual strain precisely. We obtained residual strains of both Al2O3 and YAG phases precisely as well as their azimuthal relation.
