mechanical treatments was investigated. The bcc allotrope of U, desirable due to its
irradiation withstanding characteristics, could be retained in a metastable state in this alloy
even without rapid cooling from the high temperature gamma phase. The presence of 9wt.%
of Mo in the gamma-U phase together with a homogenization annealing heat treatment at
1000° C for 24h increased the stability of the gamma phase against eutectoid decomposition …
