Multi-scale influences of as-cast microstructure heritability on intermediate/high temperature stress rupture behaviors of [111]-oriented Ni-based single crystal superalloy

Multi-scale influences of as-cast microstructure heritability on intermediate/high temperature stress rupture behaviors of [111]-oriented Ni-based single crystal superalloy

This study challenges the generally accepted principle that some degree of as-cast microstructure heritability (CMH), marked by <001> -oriented dendrite-associated inhomogeneity, is tolerable in conventional [001]-oriented Ni-based single crystal (SX) superalloys. Our findings reveal that this...
