Abstract
The structure of liquid-quenched Cu-Ga eutectoid alloy was examined by means of X-ray diffraction and compared with published results obtained on samples, quenched from the high-temperature β-phase region. Phases detected in liquid quenched samples were found to be substantially the same as those occurring during quenching of solid alloys from the β-phase region. However, the massive transformation was not suppressed during the liquid quenching procedure as it occurs in the case of rapid quenching of samples from the solid β-phase region. Diffraction patterns of martensitic phases were indexed and unit cell lattice parameters proposed. The relationship between the martensitic phases and the equilibrium ζ-phase is discussed.
