HARD PARTICLE STRENGTHENING OF REFRACTORY METALS FOR HIGH TEMPERATURE USE THROUGH INTERNAL OXIDATION

Abstract

The recrystallization temperature of 2 internally oxidized Mo-1.5 Ti alloys was determined. The alloy extruded with the lower reduction ratio of 4 to 1 had a recrystallization temperature of 2650 F, whereas the alloy extruded with a 6 to 1 ratio recrystallized at about 2400 F. Stress-rupture tests in Ar at 2200 F of 3 internally oxidized alloys recrystallized during Dynapak extrusion gave lower properties than were obtained for stressrelieved arc cast Mo-1.5 Ti. (Author)
