| Summary: | 碩士 === 國立中山大學 === 材料與光電科學學系研究所 === 103 === Friction stir processing was used to fabricate the aluminum based in situ composite from powder mixture of Al-Mg-ZnO. In the Al-Mg-ZnO composites, MgO particles were produced in situ by oxide-aluminum displacement reactions. Microstructural observations revealed the average Al grain size in the FSPed composite was about 1.10±0.61 μm.
The composite exhibits superior mechanical strength due to the large amount of nanometer-sized reinforcements in a submicron-grained matrix
after heat treatment.
