Twinning-induced shear fracture of sub-micrometer Ni-based single-crystal superalloys at 900°C

Twinning-induced shear fracture of sub-micrometer Ni-based single-crystal superalloys at 900°C

Topologically close-packed (TCP) precipitates and deformation twins significantly impact the high-temperature performances of Ni-based single-crystal (SC) superalloys. However, their contributions to failure of superalloys remain unclear. This study, utilizing in situ thermal-nanomechanical testing...
