  3. Presents the microstructure evolution in aluminum a nd copper after deformation by cold rolling in the strain range of 10 to 50 % red uction using tem and points out three types of dislocation structures are typica l and two of them are common for both materials and these two common types are f ound in non - cube grains and can be distinguished by crystallographic orientatio n of dislocation boundaries in the grains and the third type of structure is obs erved in cube grains, and concludes that grain orientation is important in deter mining the structure type but some other metallurgical parameters also have a ro le to play

    採用tem對冷軋多晶銅與多晶鋁的形變顯微組織演變進行了對比研究.結果發現：多晶銅及多晶鋁形變顯微組織中均含有三類典型的位錯結構類型，其中的兩種結構特徵在兩種材料中是相似的，這兩種類型結構存在於非立方取向晶粒，可通過晶粒中位錯邊界的晶體學取向加以區別，另一類型結構存在於立方取向晶粒；晶粒的晶體學取向決定了其形變顯微組織類型，但其它冶金學因素對顯微組織也有影響
  4. After an actual rolling process of 2050 mill was simulated by using the model, evolution laws of strain field, temperature field and microstructure were analyzed

  5. Besides the stress and strain change of metals, microstructure undergoes a series of complicated changes

    在金屬材料的熱成形中，除了經歷應力和應變的變化外，材料的微觀組織也經歷一系列復雜的變化。
  6. Based on the constitutive relationship coupled microstructure evolution, 3d - fe simulation of isothermal forging process of tc6 titanium alloy disc is performed dealing with different deformation temperature, punch velocity and shear factor of friction, effect of process parameters on equivalent strain, equivalent stress and grain size is calculated, and load - displacement curve is calculated

    本文基於微觀組織演變的本構關系模型，對不同變形溫度、凸模速度和摩擦條件下鈦合金盤的等溫鍛造過程進行了三維數值模擬，研究了變形工藝參數對等效應變、等效應力和晶粒尺寸的影響，計算了各變形條件下的位移?載荷曲線。
  7. The pore pressure, relationship of stress and strain, and the shear strength parameters obtained by unloading tests are different from those obtained by loading tri - axial tests. later the difference is analyzed in the respect of stress path and microstructure. at last, by use of a practical project the author compared and analyzed the two sets of shear strength parameters obtained by two different stress paths

    模擬基坑開挖的三軸試驗得出了與常規三軸試驗不同的孔隙水壓力和應力-應變關系，這樣得到的抗剪強度指標也低於常規三軸固結不排水加荷試驗所得抗剪強度指標，繼而本論文對抗剪強度指標的差異從應力路徑的角度和微觀結構的角度進行了分析。
