Abstract

Deformation behavior of (Nb)/α-Nb₅ Si₃ two-phase alloys is examined by high temperature compression tests. The alloys exhibit brittle fracture behavior at temperatures up to 1473 K, while reasonable compressive deformability at 1673 K. Upon high temperature compression of the alloys, the flow stress gradually decreases after the peak stress due to the recrystallization/recovery in the (Nb) phase, as well as the increase in the density of mobile dislocations within the α-Nb₅Si₃ phase. Two types of slip systems that operate in α-Nb₅Si ₃ have been identified as {011)<111] and {l)<001)<100] in the present study.
