摘 要: 研究了鎢尾礦微晶玻璃的形狀記憶效應(yīng)(SME)， 并用X 射線衍射法(XRD) 作了相分析。結(jié)果表明，鎢尾礦微晶玻璃具有明顯的SME；恢復(fù)應(yīng)變隨回復(fù)保溫溫度升高而增加；該材料隨著變形量的減小，形狀恢復(fù)率隨之上升。

Abstract:The SME of the tungsten tailings glass-ceramics has been studied. Phase indentification was done by X-ray diffraction method. The results show that the SME of the Samples is obvious. The recorery strain increases with increasing holding temperature. Moreover, the prestrain decrease, recovery of shape increases.
Key words: tungsten tailings glass-ceramics shape memory effect
