Illustrated Glossary of Fractographic Terms; Section 2: Glide Plane Decohesion, Serpentine Glide, Ripples, Stretching, Microvoid Coalescence
Abstract
The various fracture surface features formed by finescale plastic flow processes are discussed, and the mechanisms by which they are formed are discussed where they are known. Glide plane decohesion, as it has been used in the literature, is shown to be misleading, and a more descriptive term, 'stretching', is used in its place. The use of 'ductile cleavage' to describe the same process should be discontinued. Several terms have evolved to describe the surfaces created by unknown processes. Glide plane decohesion, serpentine glide, ripples, stretching, and three kinds of microvoid coalescence are shown to be parts of a spectrum of plastic rupture - the one end of the spectrum being slip on one or a few parallel planes to give separation of a large single crystal, and the other end of the spectrum being on too fine a scale for the mechanisms to be studied with present day replicas.
