本文分两部分第一部分是“从失效到设计”，从方法论角度论述三个概念──失效、性能、结构；三者之间的关系，以及分析它们的方法第二部分讨论抗三类断裂的材料设计的方法：（1）蠕变断裂──系统地开发新型合金系统；依据实验数据建立供设计使用的结构、性能和它们之间关系的表象方程（2）沿晶断裂──用归纳法建立晶界杂质浓度与固溶度之间的表象方程月准化学理论演绎晶界杂质对沿晶断裂功的影响；建立专家系统．（3）环境断裂──机理研究结果为材料的改进和设计，提供指南或准则。
From methodological point of view, the concepts of failure, property and structure are clarified, their relationship and methods of analyses discussed. The design of materials against the following three types of fracture are elucidated: (1) Creep ruptureSystematic development of new alloy systems, establishment of phenomenalogical equations about property, structure and their relationship for design purpose; (2) Intergranular fracture-Phenomenalogical equation between the grain boundary concentration of impurity and the solid solubility of the impurity is obtained by induction method; the effect of grain boundary impurity on the work of intergranular fracture is derived with quasichemical theory; and the expert system is established; (3) Environmental cracking-The results of mechanism research are used to set up the guide lines for improvement and design of materials.
