察了时效温度的影响.图3所示为不同Gd含量Mg-Gd二元合金在225 ℃的等温时效硬化曲线.从图3中也可以明显地看出,w(Gd)＜10%,合金几乎没有时效强化效果；随着Gd含量的增加,时效析出强化效果则大为改善,峰值硬度也不断提高.这一结果是由于Gd元素含量增高后,固溶淬火后合金中Gd元素的过饱和度增加,时效过程中析出相从基体中析出的驱动力增大,脱溶速度加快[12]；同时,析出相数量也增加,对基体... of magnesium matrix (precipitate volume fraction (f) of 0.04, plate or rod aspect ratio is 40:1)[66] 由此可见,若在单一析出相间作比较,β′-Mg7Gd相的强化作用是最大的,原因主要有宽厚比A较大的盘状形貌,惯习面为柱面以及析出的数量较多且细小均匀.在基面以盘状析出的γ″-Mg70Gd15Zn15及γ′-MgGdZn相虽......
