Electrical resistance, compressional strength, and extension of Ni-Mo and Ni-W alloys

Abstract

An experimental study has been made of the temperature dependences of the compressional strength of Ni alloys with 5 and 10 at.% Mo and 5 at.% W, of the kinetic curves for the electrical resistance during annealing at 400 °C, and of the nature of the tensile deformation at various temperatures. The mechanism primarily responsible for the anomalous behavior of the temperature-rate dependence of the strength of these alloys may be the formation of microscopic carbide inclusions and Cottrell carbon atmospheres at dislocations during the deformation. Presence of the K state amplifies the jumps on the flow curves.
