Deformation microstructures in {gamma}-TiAl + {alpha}{sub 2}Ti{sub 3}Al based low symmetry layered materials, with fully lamellar (FL) microstructures, have been simulated using micro-mechanical methods. In this particular effort the authors embed the specific contributions of scale and temperature dependent plastic anisotropies of individual colonies of Poly Synthetically Twinned (PST) lamellar TiAl and demonstrate their effect on overall deformation and fracture response.
