Relationship between grain size and Zener-Holloman parameter during friction stir processing in AZ31 Mg alloys Chang, C I [Institute of Materials Science and Engineering, National Sun Yat-Sen University, Kaohisung, Taiwan 804 (China)]; Lee, C J [Institute of Materials Science and Engineering, National Sun Yat-Sen University, Kaohisung, Taiwan 804 (China)]; Huang, J C [Institute of Materials Science and Engineering, National Sun Yat-Sen University, Kaohisung, Taiwan 804 (China)] 36 MATERIALS SCIENCE; FRICTION; GRAIN ORIENTATION; GRAIN SIZE; MAGNESIUM ALLOYS; PROCESSING; STRAIN RATE; X-RAY DIFFRACTION The relationship between the resulting grain size and the applied working strain rate and temperature for the friction stir processing in AZ31 Mg is systemically examined. The Zener-Holloman parameter is utilized in rationalizing the relationship. The grain orientation distribution is also studied using the X-ray diffraction.
