晶界滑移
slip at grain boundaries
晶界滑移slip atgrain botindaries相邻两晶粒在外加应力作用下沿着晶界产生的滑动。图1是晶界滑移的示意。1913年W.罗森汉和J.C.W.汉弗莱就 图1在外加切应力作用下的晶界滑移在钢的高温形变过程中观察到晶界滑移。1947年葛庭健在高纯多晶金属铝中发现一个内耗峰(在单晶中没有)，并提出其来源是由于晶粒沿晶界作粘滞性滑移所引起的应力弛豫。这一内耗峰称为葛峰。晶界滑移葛峰的发现是支持薄晶界层理论的最早的实验证明，也推动了晶界滑移的研究。近期的研究表明，葛峰与多晶金属的晶粒度有关。 晶界滑移可以用划痕方法进行直接测量。B.查默斯首先发现晶界滑移与晶界的类型和取向差有关。随后的实验进一步证实晶界滑移与晶界结构有关。图2给出金属锌以〔101印为转轴的倾侧晶界的晶界滑移量与倾侧角及温度的关系。由图2可见晶界滑移与倾侧角有关。小角晶界和某些重合晶格晶界(例如艺9(56.6。))对晶界滑移阻力很大。由图还可看出，晶界滑移与温度有关，温度越高，晶界滑移量越大。因此，晶界滑移对材料的高温力学性能丫如蠕变等)产生很大影响:了l心)1弓))倾侧艺9 f 56。615花奋p=1 96kPa亡二3屺l，1分{663K623K卦︸S翻俘犯汉)573K0占20 40印 倾侧角6(度)8《)图2锌晶界滑移与倾侧角和温度的关系 (吴希俊)
