The commonly used die-cast magnesium alloy AZ91D in chip form bearing different environmental corrosive conditions was compacted, and then extruded in order to assess the feasibility of recycling in solid-state. This recycled material showed no inferior mechanical properties than its un-chipped counterpart. It was also aging hardenable just as the original bulk material. Metallurgical investigation of the processed material showed a eutectic-like microstructure in the specimens receiving solution treatment followed by aging. This phenomenon is considered as the same as isothermal transformation in the eutectoid steel.
