Abstract

Development of high strength I/M Mg alloys has been tried by ECAE processing. The mechanical properties and microstracture of ECAE-processed Mg₉₇Zn₁Y₂ alloy with LPSO (long-periodic stacking ordered) structure were investigated. The tensile yield strength and elongation of as-cast Mg₉₇Zn₁Y₂ were improved substantially by ECAE process. ECAE-processed with yield strength of 290 MPa and elongation of 22 % was obtained. The microstracture of ECAE-processed Mg ₉₇Zn₁Y₂ alloy consisted of refined α-Mg with the grain size around 6.5 μm and finely dispersed LPSO phase. Furthermore, the some texture was formed by ECAE process. The improved mechanical properties seem to be originated by the microstracture refinement and texture.
