Abstract
It is widely recognized that grain refinement has significant influences on the strength and ductility of metals. To improve the industrialization of the severe plastic deformations (SPD) technologies for magnesium alloy, a new extrusion-shear (ES) method has been explored and widely investigated because it can manufacture ultra-fine grained microstructures in magnesium alloys. It is crucial to research the effects of process parameters on the deformation behaviors of ES process. Three-dimensional (3D) finite element modeling of ES processes with different billet temperatures and channel angles have been researched. Different billet temperatures have been regarded as the initial conditions in DEFORMTM-3D software. The strain rates evolutions have been gained with different ES process conditions. The microstructure evolution has been analyzed by the simulation and experimental results. The decreases of billet temperatures and channel angles could improve the grains refinements of magnesium alloys which have been prepared by ES process. The simulation and theoretical analysises results showed that reasonable billet temperatures and channel angles could promote grains refinements. Research results could present the fundamentals and practical guidelines for the designs of ES dies and optimization of process parameters to manufacturing high-performance magnesium rods.
