对微观断裂机理转变的研究,是对材料韧脆转变研究极其重要的一部分。微观机理的转变与宏观力学性能、断裂力学性能的转变密切相关,只有使宏微观相结合,才能更深刻地揭示转变过程的物理本质,更全面地认识材料的断裂过程和韧脆转变的意义,从而更准确地掌握和预测材料的性能,更有效地对其进行控制和设计。
The research on the change of microscopic fracture mechanism is an extremely important part of the research on the transition of ductile and brittle materials. The change of microscopic mechanism is closely related to the change of macroscopic mechanical properties and fracture mechanics properties. Only by combining macro and micro, can we reveal the physical essence of the transformation process more profoundly, understand the fracture process and the significance of the transformation of ductile and brittle materials more fully, So as to more accurately grasp and predict the performance of materials, more effective control and design.
