Abstract
Results of X-ray diffraction studies onCu-39 at.%Pd andCu-36 at.%Pd are discussed. Root-mean-square (rms) atomic displacements in an ordered B2 phase and a disordered A1 phase are determined at various temperatures. The data obtained are indicative of an anomalous state of the crystalline structure of the disordered A1 phase prior to phase transitions both in the high-temperature range of its existence and in the low-temperature metastable range. During the stress-induced phase transformation, the rms atomic displacements are found to be larger in the A1 product phase, containg abundant defects, than in the parent B2 phase.
