复相合金与复合材料中都存在着异相界面.改善基体与第二相界面的工作已成为材料研究中的重要课题.近年来在复合材料中提出的强界面结合及弱界面结合模型、基体与增强体相匹配的强化机理等在复相合金中也同样适用.这些研究涉及界面物理及界面化学,也包括界面的原子结构及电子状态.程开甲先生认为通常的TFD模型在材料设计、电子输运现象等实用领域中不完善,似乎是在处理原子条件中,特别是在固体中原子的边界条件处理上有一些错误,正确的边界条什是存在的,只是一直未找到.程开甲指出,原子的边界条件
Heterogeneous alloys and composite materials exist heterogeneous interfaces.Improvement of the interface between the matrix and the second phase has become an important issue in the research of materials.In recent years in the composite materials proposed strong interface bonding and weak interface bonding model, The strengthening mechanism matching reinforcements is also applicable in complex phase alloys. These researches involve interfacial physics and interfacial chemistry as well as the atomic structure and electronic states of the interface. In his opinion, the usual TFD model is of great importance in material design, electron transport It seems that there are some mistakes in dealing with the atomic conditions, especially in the treatment of the boundary conditions of solids, and the correct boundary conditions exist but have not been found. Cheng Kai-A pointed out that atoms Boundary conditions
