1. Strain hardening effect
   應變硬化效應
2. The results indicated that , the fabrication process of ultra - fine grain material is mainly determined by the stress , rotate speed and the flux of cooling water . the grain refining and the hardening effect are mostly affected by the rotate speed and the flux of cooling water . compared with commercial ly12 , the invalidate strength and the prolongation rate of the ultra - fine grain material are properly improved in the measurement of compression property ; and the abrupt change of the dilatability of the ultra - fine grain material at 500c is found ; also the phenomena of which the grain size of these microstructures is stable when annealed under 300c is observed
   研究表明，采用本文提出的摩擦壓扭強變形區(qū)轉(zhuǎn)移法可以得到棒狀的超細晶材料，軸向壓力、扭轉(zhuǎn)速度和溫度是采用該方法制備超細晶材料的主控參數(shù)；試件的旋轉(zhuǎn)轉(zhuǎn)速和冷卻速度對變形區(qū)晶粒細化和硬化效果影響顯著；超細晶ly12的壓縮性能與淬火+自然時效狀態(tài)的ly12壓縮性能相比，斷裂強度和延伸率均有一定程度的增強；超細晶ly12的熱膨脹系數(shù)在550左右發(fā)生明顯的變化。
