Influence of micro- and nanoparticles on mechanical properties of magnesium and magnesium alloys

Abstract

Abstract Magnesium and magnesium alloys were reinforced with various micro- and nanoparticles (SiC, Inconel718, AI2O3, ZrC2, BN, graphite) Composites were prepared by squeeze casting and using powder metallurgy followed by hot extrusion. Tensile and compression tests were performed at elevated temperatures up to 300 °C. The influence of micro- and nanoparticles on mechanical characteristics is discussed on the base of physical models. Bonding at the interface between particles and magnesium matrix plays an important role for the resulting composite properties.
