Deformation twinning in the full-α″ martensitic Ti–25Ta–20Nb shape memory alloy
Source abstract
Abstract
Deformation twinning of the Ti–25Ta–20Nb (mass%) shape memory alloy is characterized using EBSD and TEM. The selfaccommodating α″ microstructure is shown to be first deformed using \111\α″ type I and α″ type II reorientation twinning. Plastic deformation occurs further by plastic twinning with a new \130\ α″ twinning system. Maximum lattice deformation calculation is a relevant parameter to predict the variant of martensite that is favored during the reorientation process. Conversely, Schmid factor analysis can be used to predict the selection of \130\ α″ twinning variants during deformation. Analogy between \130\ α″ and \332\ β twinning systems is highlighted
