本文采用差示扫描量热法(DSC)对CuAlNi-43~#合金中马氏体转变的动力学过程进行了探索性的研究。从计算机对实验数据的拟合及判断得出:该转变符合形核。长大(n=1.5),f(α)=3/2(1-α)[-1n(1-α)]~(1/3)的规律。并求得转变活化能为E=53.0kJ/mol,表观指数前因子A=1.2×10~(14)。
In this paper, the kinetics of martensitic transformation in CuAlNi-43 ~ # alloy has been explored by differential scanning calorimetry (DSC). From the computer to the experimental data fitting and judging: the change in line with the nucleus. (N = 1.5), f (α) = 3/2 (1-α) [-1n (1-α)] ~ (1/3). The activation energy of transformation was calculated as E = 53.0kJ / mol, and the apparent index factor A = 1.2 × 10 ~ (14).
