Microvoid coalescence : ウィキペディア英語版 | Microvoid coalescence
Microvoid coalescence (MVC) is a high energy microscopic fracture mechanism observed in the majority of metallic alloys and in some engineering plastics. ==Fracture process==
MVC proceeds in three stages: nucleation, growth, and coalescence of microvoids. The nucleation of microvoids can be caused by particle cracking or interfacial failure between precipitate particles and the matrix. Microvoids grow during plastic flow of the matrix, and microvoids coalesce when adjacent microvoids link together or the material between microvoids experiences necking. Microvoid coalescence leads to fracture.〔Hertzberg, Richard W. ''Deformation and Fracture Mechanics of Engineering Materials, Fourth Edition''. John Wiley and Sons, Inc, Hoboken, NJ: 1996.〕
