  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

  3. The results indicated : 1 ) the friction interface can transfer continuously and stably with the imbalance cooling thermo - induce. ultra - fine grain column part can be prepared through it. and ultra - fine grain flat part can be obtained through jointing several ultra - fine grain strips in cooling friction stir processing 2 ) the refined grain size and the hardening result are mostly affected by the rotate speed, the friction press and the deformating temperature

    實驗結果表明： （ 1 ）通過不平衡冷卻的熱誘導作用，實現了棒材摩擦界面的持續、穩定轉移，得到了棒狀超細晶組織；通過強冷攪拌摩擦工藝進行細晶帶合併，能夠得到板狀的超細晶組織。
  4. The tensile and compression experiment on bulk nanocrystalline ag prepared by igc method was carried on mt810 with different grain sizes and zwick 10tn2s machine at different strain rates under normal temperature respectively. the stain rate sensitivity m was found to be 0. 025, which was extremely lower than the ordinary values. also the work hardening exponent is very low

    本文從用惰性氣體蒸發冷凝和真空原位壓結法（ igc ）制備得到的直徑80mm ，厚度7 . 6mm的大尺寸納米晶金屬ag樣品上切割得到符合力學實驗要求的拉伸和壓縮試樣，在mts810和zwick精密力學測試機上分別精確測定了拉伸和壓縮應力?應變曲線與晶粒尺寸和應變速率的關系。
  5. Using the method in quantification metallography, the size of grain and hardening particles, volume percentage of inclusions and hardening particles are estimated according to samples

    在解剖被檢試樣的基礎上，運用定量金相學的分析方法，估算了被檢部位的晶粒直徑、夾雜物體積百分數、強化粒子直徑及體積百分數。
  6. Simulating on polycrystalline cyclic deformation indicates that hardening first appears at grain boundary then spreads to grain inside. finally, hardening is not well - distributed in the specimen when deformation is limited

    循環塑性模擬對于多晶材料的bauschinger效應和晶粒間硬化過程以及硬化在試樣上的非均勻分佈給出了相應的描述。
  7. In addition, the cyclic softening under the strain amplitude less than 0. 8 % can be explained by " grain - rotation induced cyclic softening ", and the cyclic hardening in the higher strain amplitude was attributed to twinning

    在低應變幅區，合金在室溫下的低周疲勞性能明顯優于在400下的低周疲勞性能。但隨著應變幅的增加，室溫和400下合金的疲勞壽命趨于接近。
