DOI: 10.1002/adem.202400214

Abstract: The microstructure and texture are investigated for nanocrystalline Au‐13at%Pd deformed by high‐pressure torsion. The grain size of this alloy is observed to remain below about 20 nm when subjected to severe plastic deformation. Surprisingly, the initial… read more here.

DOI: 10.1016/j.ijplas.2018.10.012

Abstract: Abstract In diffuse-interface (phase field) models of polycrystalline solids, the grain boundaries naturally possess a narrow region of finite thickness. A Ginzburg-Landau type kinetic equation for plastic deformation of a solid is derived that combines… read more here.

DOI: 10.1016/j.mtla.2018.100189

Abstract: Abstract Grain boundary sliding has a substantial contribution to high temperature deformation of α/β titanium alloys. Despite the low homologous temperature, the operation of grain boundary sliding is presently reported at room temperature using a… read more here.

DOI: 10.1016/s1003-6326(20)65483-8

Abstract: Abstract The aim of present work is to develop a crystal plasticity modeling approach to integrate slip, dynamic recrystallization (DRX) and grain boundary sliding (GBS) for simulating the deformation behavior and texture evolution of magnesium… read more here.
