Abstract: | The structural change of metallic glass Cu45Ti55 from room temperature to 800 K is investigated by combining internal friction using the torsion penulum method with X-ray
diffraction (XRD), differential scanning calorimetry (DSC), and transmission electron microscopy (TEM). The internal friction
curve exhibits a point of inflection at about 640 K and an internal friction peak between 640 and 780 K, which corresponds
to the precipitation of CuTi2 (tetragonal) and a metastable phase I (tetragonal) and the formation of CuTi (tetragonal), respectively. The result shows
that internal friction is closely related to the phase transition during crystallization, and there is much correspondence
between internal friction and DSC in describing the crystallization behavior of metallic glasses. |
