| Abstract Scope |
The microstructure and texture evolution during rotary swaging of as-cast Mg-0.5 wt.% Ce alloy were studied using x-ray diffraction and orientation imaging microscopy in a scanning and transmission electron microscope. Finite element method simulations captured the complex deformation process while full-field and mean-field crystal plasticity simulations predicted the refined microstructure and characteristic texture evolution. Profuse {10-12} twinning contributed to initial grain refinement, followed by extensive operation of non-basal slip, contributing to grain size reduction from ~500 μm to ~0.5 μm and an increase in hardness from 35±4 to 55±3 HV for a strain of 0.9 in three steps of swaging. A progressive evolution of fiber texture, with the c-axis oriented perpendicular to the swaging direction, was observed with increasing strain. Multi-scale simulations indicated the accommodation of complex localized deformation due to swaging by the operation of pyramidal <c+a> slip, promoting significant grain refinement and the formation of a distinct texture. |
