抄録
The effects of powder consolidation and extrusion temperatures on the microstructure and the tensile properties of hot extruded ZK61 alloy powder were investigated. The powder was produced by the rapid solidification technique of spinning atomization. Consolidation of the powder was done using the spark plasma sintering process at 200, 300 and 400 ℃. Hot extrusion was then performed at 250, 300 and 400 ℃. The tensile properties were then evaluated and correlated to the Microstructural features, i.e. grain size. The results show that the use of rapidly solidified atomized powder could lead to improved mechanical response as a result of the refinement of both grain and precipitated compounds which are obtained through the use of powder metallurgy process. These results, along with other previously reported studies, prove that powder metallurgy technique can help to extend the applications of Mg-alloys in higher load carrying components.
