Tensile properties and fracture characteristics of spray cast alloy IC6 (Ni-7.8Al-14Mo-0.05B)

摘要

Tensile testing results of spray cast Ni3Al-based superalloy indicated that the yield strength and tensilestrength increase with the increasing of temperature and reached maximum at around 760., then decrease withthe increasing of temperature. After high temperature isostatic pressing (HIP), yield strength decreased and ductilityand tensile strength increased. Stereographic projection showed that no matter at room temperature, mediumtemperature or high temperature, cracks extend along (111).
