纯镁片在400℃和300℃下分别进行8个循环和4个循环的ARB处理。由于较高的变形温度、中间二次加热和空冷，组织在第一次循环中被细化，而在随后的ARB工艺中才趋于均匀。ARB工艺对纯镁板材的拉伸性能没有明显的影响，这是由于ARB过程中晶粒度稳定、基面织构占优势所致。为了提高板材的粘接质量，应引入进一步的变形。(C)2010爱思唯尔B.V.保留所有权利。
The pure Mg sheets were processed by ARB at 400 degrees C and 300 degrees C up to 8 cycles and 4 cycles, respectively. The microstructure was refined during the first cycle and only homogenized during the following ARB process due to the high deformation temperature, intermediate reheating and air-cooling. The ARB process did not show an obvious effect on the tensile properties of the as-ARBed pure Mg sheet due to the stable grain size and dominant basal plane texture during ARB. Further deformation should be introduced to improve the bonding quality of the as-ARBed sheet. (C) 2010 Elsevier B.V. All rights reserved.
