In this work, we build the model and derive the theory of nonlinear deformation for substitutional alloy AB with interstitial atom C and face-centered cubic structure under pressure from the statistical moment method. The calculation results for FCC-AuCuSi are presented. We obtain the values of density of deformation energy, maximum real stress, limit of elastic deformation, and the stress-strain curve and compare the calculated results with experiments and other calculations.

统计矩量法研究FCC-AuCuSi在压力下的非线性变形

在这项工作中，我们建立了模型，并从统计矩方法中推导了具有间隙原子C和面心立方结构的替代合金AB在压力下的非线性变形理论。给出了FCC-AuCuSi的计算结果。我们获得了变形能量密度，最大实际应力，弹性变形极限以及应力-应变曲线的值，并将计算结果与实验和其他计算进行了比较。
