• 中文摘要： 反覆之機械外力或於麻田散體變態溫度範圍內之冷熱交互作用均可導致形狀記憶合金的疲勞現象。其效果大小因作用之溫度範圍而異：端視在穩定之沃斯田體高溫相及或在麻田散體低溫相及或係在足以引起應力誘生相變態的範圍而有不同。本文對形狀記憶合金由硬化及裂罅的形成之〝機械疲勞〞以及因相變態溫度的轉移及記憶性質的消失之〝形狀記憶痠勞〞，加以界定。並對上述諸現象之組織變化加以探討。
• 英文摘要： Fatigue of SMA can be caused by thermal cycling through the range of martensitic transformationor by mechanical cycling. The effects differ depending on the temperature range: stable high temperaturephase (austenite), or low temperature phase (martensite), or the range where stress induced transformationcan take place. A distinction is made between mechanical fatigue and shape-memory fatigue,i.e. hardeningand crack formation, or a shift in transformation temperatures and loss of memory. The microstructuralorigin of all phenomena is discussed
