一种镁合金矩形截面条材的矫直方法
摘要：
一种镁合金矩形截面条材的矫直方法，该方法包括下述步骤：（1）判断该镁合金矩形截面条材是否具有可矫性（2）计算该镁合金矩形截面条材的最大弯度δmax；（3）用弯度塞尺对该镁合金矩形截面条材进行弯度评级，在该镁合金矩形截面条材的弯度小于δmax的情况下，对该镁合金矩形截面条材进行矫直；（4）确定压下量△H；（5）将该镁合金矩形截面条材整体压平，然后继续施压，令其在厚度方向发生少量的塑形变形△H，卸去压力后该镁合金矩形截面条材实现矫直且残余应力得以消减。该方法是能够针对镁合金矩形截面条材的快速且能有效消减残余应力的矫直方法。
摘要（英）：

A straightening method for a magnesium alloy rectangular section bar stock includes the following steps: (1) determining whether the magnesium alloy rectangular section bar stock has rectifiability; (2) calculating the maximum camber delta max of the magnesium alloy rectangular section bar stock; (3) conducting camber rating on the magnesium alloy rectangular section bar stock with a camber feeler gauge, and straightening the magnesium alloy rectangular bar stock if the camber of the magnesium alloy rectangular section bar stock is smaller than delta max; (4) determining a rolling reduction delta H; and (5) flattening the magnesium alloy rectangular section bar stock, and then continuing to press to generate a small amount of plastic deformation delta H in the thickness direction, and removing the pressure, so as to realize straightening of the magnesium alloy rectangular bar stock and reduce residual stress. The straightening method can quickly and effectively reduce the residual stress of the magnesium alloy rectangular section bar stock.
