Phase-formation maps of CuZrAlCo metallic glass explored by in situ ultrafast techniques

Popis výsledku v původním jazyce

Crystallization of Cu47.5Zr48Al4Co0.5 metallic glass upon isokinetic and isothermal annealing is studied by conventional and ultrafast differential scanning calorimetry, resistive flash-annealing, and in situ high-energy X-ray diffraction. The fast-heating experiments of Cu47.5Zr48Al4Co0.5 metallic glass are complemented by in situ high-energy XRD studies of the undercooled liquid by using electromagnetic levitation. The combination of complementary techniques reveals a competition between the Cu10Zr7, B2 CuZr and t4 Cu2ZrAl phases crystallization depending on heating rate and shows the specific role of Co alloying. A continuous-heating-transformation diagram for a heating rate exceeding six orders of magnitude, h = 0.0833 - 90 000 K s-1, and a time-temperature-transformation diagram are constructed.
