“…The allotropic phase transformation from the hexagonalclose-packed ͑hcp͒ phase to the face-centered-cubic ͑fcc͒ phase of bulk cobalt ͑Co͒, fcc heating cooling hcp, has been studied by x-ray diffraction ͑XRD͒, 1 electron diffraction, 2 acoustic measurements, 3 and by theoretical calculation. 4 From XRD, the phase-transition temperature was found to be at 417°C, with considerable hysteresis between 390-430°C.…”

“…14) The Q À1 int is an intrinsic part which is composed of the internal friction contributions of each phase and is strongly dependent on microstructural properties, especially in the martensite phase. The tan 0 at the peak in the two-phase state, which corresponds to the temperature region from M s (A s ) to M f (A f ), strongly depends on the Q…”

“…Viatte et al [5] pointed out that the high resistance to the deformation is mainly due to the carbide-carbonitride part of the cermets. On the other hand, the martensitic phase transformation (hc <-> fcc) of pure cobalt [6] does not exist in nickel.…”
