Abstract
The retention of the ..beta..-Be phase at room temperature by the use of a rapid quench technique opens the way for a full investigation of its physical properties. Studied were thermal response, hardness, electrical resistivity, structural analysis, and superconductivity. Preliminary work indicates that the stabilization of the ..beta..-Be structure at room temperature is a very sensitive function of Ni content. This sensitivity is illustrated by the fact that the Be/sub 92/Ni/sub 8/ sample is mainly ..cap alpha..-phase while the Be/sub 91/ /sub 8/Ni/sub 8/ /sub 2/ is almost completely ..beta..-phase. Retention of the ..beta..-structure apparently requires the exact eutectoid composition and a high quench rate.
