Triple grain boundary
WebStronger stalks that improve standability for harvest. A focus on selecting tall and robust hybrids that have high grain yield and are 100–200 CHU longer in maturity than normal … WebWe are often preoccupied with grain boundaries, but triple junctions may be even more important in the sinter-ing process since these may be open pipes for transporting material. Part of the reason for this bias is that triple junc-tions are very difficult to study and to model (see Section 14.9).

WebNov 4, 2024 · High grain boundaries also pose to have excessive hardness and internal strength at the expense of ductility and toughness, thereby subjecting the grain to the point of crack initiation [44]. It ... Web3.2.3 grain boundary intersection count—determination of the number of times a test line cuts across, or is tangent to, grain boundaries (triple point intersections are considered as 11⁄ 2 intersections). 3.2.4 image processing—a generic term covering a variety of video techniques that are used to enhance or modify
WebSep 16, 2024 · Grain boundary energies can be extracted from 3D images by measurement of dihedral angles at triple lines and by exploiting the Herring equations at triple junctions. The population of... WebThe first scientific paper detailing the triple junction concept was published in 1969 by Dan McKenzie and W. Jason Morgan. The term had traditionally been used for the intersection of three divergent boundaries or spreading …
