在这本书中，作者专注于解理断裂的物理性质的描述，为科学家，工程师和学生提供一个全面的物理模型，生动地描述了解理微裂纹过程中操作的局部（微观）规模的缺陷之前。对临界事件和解理断裂判据的描述将指导读者如何控制解理过程和优化微观组织以提高金属材料的断裂韧性。* 在局部（微观）尺度上操作的解理断裂的物理（机械）过程，重点是裂纹成核和裂纹在颗粒/晶粒和晶粒/晶粒边界上的扩展 * 临界事件，即，微观结构对解理断裂的影响，包括晶粒尺寸、第二相粒子和晶界的影响，对TiAl合金和TiNi记忆合金脆性断裂的综合描述
In this book the authors focus on the description of the physical nature of cleavage fracture to offer scientists, engineers and students a comprehensive physical model which vividly describes the cleavage microcracking processes operating on the local (microscopic) scale ahead of a defect. The descriptions of the critical event and the criteria for cleavage fracture will instruct readers in how to control the cleavage processes and optimize microstructure to improve fracture toughness of metallic materials. * Physical (mechanical) processes of cleavage fracture operating on the local (microscopic) scale, with the focus on the crack nucleation and crack propagation across the particle/grain and grain/grain boundaries* Critical event, i.e., the stage of greatest difficulty in forming the microcrack, which controls the cleavage fracture* Criteria triggering the cleavage microcracking with incorporation of the actions of macroscopic loading environment into the physical model* Effects of microstructure on the cleavage fracture, including the effects of grain size, second phase particles and boundary* Comprehensive description of the brittle fracture emerging in TiAl alloys and TiNi memory alloys
