Abstract
- The effect of equal channel angular extrusion (ECAE) on the mechanical behavior of AM60/Al<subscript>2</subscript>O<subscript>3p</subscript> magnesium metal–matrix nanocomposites was investigated. ECAE is a useful technique to produce bulk nanostructured materials through severe plastic deformation. The present magnesium metal–matrix composites (Mg MMCs) with 1 wt% nanosized Al<subscript>2</subscript>O<subscript>3</subscript> particles for ECAE were fabricated using stir-casting method. The significantly enhanced mechanical behavior of AM60/Al<subscript>2</subscript>O<subscript>3p</subscript> magnesium metal–matrix nanocomposites at room temperature, for instance, yield strength (YS), ultimate tensile strength (UTS), and ductility, can be obtained after ECAE process. The AM60/Al<subscript>2</subscript>O<subscript>3p</subscript> MMC after 4 passes of ECAE exhibited greater YS, UTS, and ductility (+135%, +107%, and +245% increase, respectively) than those of as-cast AM60. Experimental results show that the AM60/1wt %Al<subscript>2</subscript>O<subscript>3p</subscript> MMC after 4 passes of ECAE exhibits the superior mechanical behavior. [ABSTRACT FROM AUTHOR]
