The fcc to hcp transition induced by mechanical deformations in the Ni–Ru system


The structural transition between the metastable fcc and hcp crystalline solid solutions in the Ni–Ru system has been studied as a function of composition using the mechanical alloying technique. At the transition point, the spacings between the close-packed planes of the metastable fcc and hcp phases are the same. No amorphization is observed at the interfaces. This mechanically induced phase transition has been studied by x-ray diffraction, transmission electron microscopy, and differential thermal analysis.
