Silver-uranium system

Abstract

The phase diagram of t he syst em silver-uranium was constru cted from dat a ob tained b y t hermal analysis, metallographic examinat ion, and X-ray diffrac tion. The syst e m is characte ri zed b y a eute ct ic having a composition of approximately 5 weight percent of uranium occurring at 950 0 C, and a monotectic occ urring a t 1,132 0 C, and 0.23 weight percen t of silver. The solid solubility of uranium in silve r appeared t o be between 0.1 and 0.4 weight percent a t the eu tect ic te mperat ure; no appreciable solubility of silver in uranium_ was noted . The te mperat ures of t he gamma-beta a nd t he beta-alpha t ransformat ion of uranium appare nt ly were unaffe cted by silver .
