采用三种等通道角挤压（ECAE）工艺路线加工镁合金。测定了加工后坯料的抗拉强度、晶粒尺寸和织构，探讨了加工方式对坯料力学性能的影响及其强化机理。A路线是唯一可以通过ECAE增加强度的路线。采用多温度ECAE工艺制备了亚微米组织和织构强化相结合的高强度镁合金。(C) 2008材料学报Elsevier Ltd.出版。版权所有。
Three processing routes of equal channel angular extrusion (ECAE) were used to process Mg alloy. Tensile strengths, grain sizes and textures of these processed billets were measured to investigate the effect of processing route on the mechanical properties, and the strengthening mechanism. Route A is the only route that can increase the strength by ECAE. A multiple-temperature ECAE procedure has been developed to produce high-strength Mg alloy, which is a combined result of submicron grain structure and texture strengthening.
