段玉华 %A 葛庭燧 %A 张天宜 %J 物理学报 %D 1993 %I %X Anelastic creep curves of 110] symme rical tilt boundaries with mis-orientation angles 60°and 153.4°in aluminium bicrystals has been measured in torsion. It was found that the relaxation strength associated with the boundary becomes zero below a temperature T0 which has a value of about one half of the melting temperature Tm of bulk aluminium. This shows that a perceptible change of the internal structure of the grain boundary has taken place around this temperature. %K 铝 %K 晶粒间界 %K 弛豫 %K 转变温度 %U http://www.alljournals.cn/get_abstract_url.aspx?pcid=6E709DC38FA1D09A4B578DD0906875B5B44D4D294832BB8E&cid=47EA7CFDDEBB28E0&jid=29DF2CB55EF687E7EFA80DFD4B978260&aid=9AF0CD577233C754399DBCE93F6ED92D&yid=D418FDC97F7C2EBA&vid=ECE8E54D6034F642&iid=0B39A22176CE99FB&sid=E42CAFB11D4BE21A&eid=358F98408588E522&journal_id=1000-3290&journal_name=物理学报&referenced_num=2&reference_num=6
