Micromechanism of Cleavage Fracture of Metals A Comprehensive Microphysical Model for Cleavage Cracking in Metals
Auteurs : Chen Jianhong, Cao Rui
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.

R. Cao, Dr. of Engineering, is a professor in the Faculty of Materials Science and Engineering of Lanzhou University of Technology in China. She has been investigating the fracture behavior of TiAl alloys and welded dissimilar metals since 2000 and published more than 25 papers on these subjects in international journals.
- 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
