Improving the property profile of a bioresorbable Mg-Y-Nd-Zr alloy by deformation treatments

Abstract

The effect of three deformation methods (equal channel angular pressing (ECAP), multiaxial deformation (MAD), and rotary swaging (RS)) on the structure, texture, mechanical and corrosion properties of magnesium alloy WE43 (Mg-3.56%Y-2.20%Nd-0.47%Zr) was studied. Microstructure, texture, and mechanical properties were in- vestigated by optical and transmission electron microscopy, X-ray diffraction, and tensile testing, respectively. Corrosion resistance was evaluated by a combination of mass loss and hydrogen evolution measurements, as well as electrochemical testing
