摘要

α_Zr→α_Zr+β_Zr phase transformation kinetics were investigated by the thermodilatometry at various heating rates in Zr-1Nb-0.01Cu alloy. The results show that the relationship between the start transformation temperature of α_Zr→α_Zr+β_Zr and the heating rates is T_α→α+β=744.4+9.4ln(R_H), and the heating rates show a weaker effect on the transformation temperatures of the alloy than on that of E110 alloy. The active energy of α_Zr→α_Zr+β_Zr is 149.1 kJ/mol calculated from the JMA model, smaller than that of Zr-4 and M5 alloys. The continuous heating transformation diagram (CHT) of α_Zr→α_Zr+β_Zr is given according to phase transformation curves of the alloy.
