Mechanical properties of refractory metal wires for high temperature reinforcement

Abstract

The tensile and stress-rupture characteristics of some refractory metal wires potentially useful for the reinforcement of high temperature superalloys have been determined. The room temperature tensile properties are largely dependent on the degree of deformation of the material and this is reflected in the increase in tensile strength with decrease in wire diameter. In creep rupture at elevated temperature a tungsten alloy is the stronger material. There is no apparent correlation between room or elevated temperature short-time tensile strength and creep-rupture strength.
