摘要 应用Levenberg-Marquardt(L-M)算法进行相图的计算。L-M算法能够实现计算精度和收敛速度的最佳结合,并对初始值的选取不敏感。用L-M算法计算所得的三元Al-Si-Mg合金相图与实验相图吻合得很好。 The Levenberg-Marquardt method is applied to calculate the stable phase equilibria. The optimal combination of high precision and fast convergence for calculation is achieved by this method, which is not sensitive to the initial values. The phase diagram of ternary Al-Si-Mg system from calculation by L-M method is well fitted with the experimental results.
