提出了二元系统界面和晶界处固态非晶化（SSA）的热力学模型。已经证明，晶体-非晶界面的能量通常低于晶体-晶体界面的能量。只要非晶产物层不太厚，这种效应就为SSA提供了驱动力。该模型已应用于多种二元晶体-晶体系统和二元晶体-非晶系统，以预测是否会发生界面和/或晶界非晶化并计算非晶层的最大厚度。所得结果与文献报道的实验数据一致。 \textcopyright{} 1996 美国物理学会。
A thermodynamic model for solid-state amorphization (SSA) at interfaces and grain boundaries in binary systems has been proposed. It has been demonstrated that the energy of a crystalline-amorphous interface is, in general, lower than the energy of a crystalline-crystalline interface. This effect provides the driving force for SSA, as long as the amorphous product layer is not too thick. The model has been applied to several binary crystalline-crystalline systems and binary crystalline-amorphous systems to predict whether or not interface and/or grain boundary amorphization can occur and to calculate the maximum thickness of the amorphous layer. The results obtained agree with experimental data reported in the literature. \textcopyright{} 1996 The American Physical Society.
