EFFECT OF SMALL ADDITIONS OF IRON, SILICON, AND ALUMINUM ON THE HARDNESS AND DEFORMATION OF CAST URANIUM AT ELEVATED TEMPERATURES: STATISTICAL EVALUATION

摘要

Mechanical property data from 27 cast alloys of the U-Fe-Si-Al system were statistically evalu¬ated. The alloy levels were 300 and 1000 ppm. Hardness and drop hammer values were obtained at temperatures ranging from 885 to 1200°F. Both resistance to deformation and hardness values decreased as temperatures increased and increased as the silicon level increased.
