Abstract Scope |
Metal matrix nanocomposites are attracting attention because of their great potential for improved mechanical properties or possible functionalization. These hybrid materials are often produced by casting processes, but they can also develop their property profile after hot working, e.g. by forging or extrusion. In this paper a commercial cast magnesium alloy AM60 is enriched with 1 wt.% AlN nanoparticles and extruded into round bars with varied extrusion rate. The same is carried out with the unreinforced AM60 in order to be able to determine the influences of the AlN nanoparticles in direct comparison. The influences of extrusion speed on the recrystallization behavior as well as of nanoparticles on the microstructure evolution and particle induced strengthening are discussed and assessed with respect to the resulting mechanical performance. |
