提出了一种新颖的轧制方法，通过在轧制过程中铺设波形模来实现镁合金轧制板材的弱基面织构。结果表明，经波形模压(WDR)处理的镁铝锡(AT63)合金板材具有低强度的基面织构和倾斜的基面峰。在WDR过程中发现在单次通过后发生了显著的基面织构弱化。此外，WDRed合金板材表现出从中心到表面的基面织构梯度，反映了板材在轧制过程中的不对称变形模式。拉伸试验表明，WDRed AT63板材的应变硬化能力(n=0.295)和断裂伸长率(εf=922.5%)明显高于未采用波形模轧制的AT63板材。
An innovative rolling approach was proposed to achieve weak basal texture in rolled Mg alloy sheets, by laying a wave-shaped die during rolling. It was shown that, Mg–6Al–3Sn (AT63) alloy sheets processed by this wave-shaped die rolling (labeled as WDR) exhibited basal textures with low intensity and tilted basal peak. A substantial basal texture weakening was found to occur during WDR after a single pass. Moreover, the WDRed alloy sheets exhibited basal texture gradients through the center to the surface, reflecting the asymmetric deformation mode of the sheets during rolling. In addition, WDR was effective to refine the grain size of AT63 alloy, from ~ 35 μm to ~ 10.3–11.5 μm. Tensile tests revealed that, the WDRed AT63 sheets presented much enhanced strain hardening ability (n= 0.295) and high elongation to failure (εf= 22.5%), as compared with the equivalent AT63 sheet rolled without wave-shaped die.
