Metastable phases in the uranium-molybdenum system and their origin
K. Tangri,G.I. Williams +1 more
TL;DR: In this paper, the alpha uranium lattice with increasing molybdenums additions has been determined and the relationship between observed structures and their origin is deduced from a study of the effect of cooling rates in producing alternative structures, and it is shown that the structures γ° and α'', in order, are progressive stages in the generation of α' from the bec γ phase.
