| Outline of Final Research Achievements |
In this study, the single-crystal micropillar was prepared by Mo5SiB2 (T2) phase in Mo-Si-B three phase alloys. The effect of off-stoichiometry on the deformation and fracture behavior of T2 at room temperature was studied by micro-compression tests.
Elastic moduli of each constitution phases of the Mo-Si-B alloys were estimated by using the macroscopic elastic constant, volume fraction of each constitution phases and the rule of mixtures. The effect of the off-stoichiometry on elastic moduli of T2 phase were investigated.
