交叉轧制
一种加工工艺:先将板材沿一个方向轧制,然后沿与第一方向成 90° 的方向轧制,如此交替进行。经过多次轧制道次,直至达到所需厚度。该工艺可形成更均匀的晶粒组织,从而降低钛等正交各向异性材料性能的方向性(即材料的正交各向异性程度降低)。
Cross rolling
A process in which plate material is alternately rolled one direction and then rolled at 90° to the first direction. Multiple passes are made until the desired thickness has been achieved. This produces a more uniform grain structure, thereby reducing the directionality of properties for orthotropic materials such as titanium (i.e., the materials become less orthotropic).
