Notes:
Grain refinement of magnesium alloy by Friction Stir Processing (FSP) was investigated. Itis assumed that dynamic recrystallization (DRX) is occurred by frictional heat and plastic flow duringFSP. This process is the effective method of the grain refinement for light metals. In this study, FSPwas conducted to cast Mg alloys for and the difference of the grain refinement by DRX in these alloyswas examined. As a result, in comparison with commercial Mg-Al-Zn alloy and Mg-Y-Zn alloy havefiner microstructure. The grain size of FSP-ed Mg-Y-Zn alloy was ~1.7 [/m], however, that of AZ31alloy was 20~30 [/m]
