Development of Dispersion-Strengthened Nickel-Base Sheet Alloys.
Abstract
Dispersion-Strengthened Ni-15Mo-ThO2 sheet was rolled from plate which was made by pressing, canning and extruding powders prepared by spray drying and selective reduction. Good ThO2 dispersions and strongly developed crystallographic textures were both necessary for good strengths at 1093 degrees C. The yield strength for Ni-15Mo-3ThO2 sheet with 200 degrees A average ThO2 diameter was 23.2 ksi at 1093 degrees C. The stress for fracture in 100 hours at 1093 degrees C in vacuum was 13.5 ksi. Attempts to make a Ni-20Cr-2ThO2 sheet with good strength at 1093 degrees C were unsuccessful. (Author)
