Abstract
Thermal stability of the beta Cu-Al-Be phase with an eutectoid composi tion was studied by thermoelectric power measurements. Depending on th e aging temperature, precipitates of the alpha(2) and gamma(2) phases were identified by optical and electron microscopies. From these resul ts, C curves were deduced in a TTT diagram and a peritectic beta-->alp ha(2) transition temperature was deduceed to be close to 275 degrees C .
