  3. The electric field strengthens the laminate boundary of 2090 alloy. the laminate strengthening mechanism translates into boundary strengthening and grain inner toughening with more ductility fracture and less intergranular fracture. the ductility property is enhanced with no change of intensity

    對鋁理合金sem實驗發現，電場固溶和時效強化了晶界，和晶內塑性的改善，斷裂特徵出現由分層沿晶斷裂向塑性斷裂轉變，斷麵塑性變形特徵增加。

    結果表明，成型模裂紋斷口形態呈沿晶特徵，沿晶面上有細小析出物，為脆性斷裂。
  6. The presence of small amount of liquid at grain boundaries tends to form thin viscous layer which surrounds the finer grains. intergranular fracture may occur at the grain boundaries between two fine grains not covered by viscous phases. the high ductility achieved at low strain rates is generally attributed to dislocation glide - creep accommodation mechanisms

    原始晶界上產生少量液相，形成薄的固液共存粘性層並包圍細化的晶粒，沿晶斷裂主要發生在無粘性層的細晶粒間；而在較低應變速率下，三叉晶界位錯攀援?蠕變協調機制鬆弛晶界滑移產生的應力集中，晶界上產生較多液相，有利於晶界滑移進行。
  7. The impact of random grain boundary distribution and connectivity on intergranular fracture of polycrystalline materials

    隨機晶界分佈和連通性對晶間破壞行為的影響
  8. Above analysis can provide instructions for grain boundary design and controlling in grain boundary engineering. dynamics intergranular fracture process is modeled with considerations of grain boundaries damage

    通過考慮晶界損傷，進一步對拉伸試樣破壞單元的動態沿晶斷裂過程進行了數值模擬分析。
  9. The network carbide and acicular martensites that existed in the microstructure of the root grooves of the spline due to improper carburating and quenching process of the shafts, led to the initiation and propagation of the intergranular microcracks and were the main reason that caused the early fracture of the shafts

    由於滲碳淬火工藝不當，在二軸花鍵槽根部的組織中產生了網狀破化物和粗大的針狀馬氏體，在外力作用下形成沿晶顯微裂紋並擴展，是導致二軸疲勞斷裂的主要原因。
  10. It is found that the electric field improves elongations in 1420 alloy markedly, but has little effect on strengths. at the same time, the electric field lessenes percentages of intergranular delamination and increases transgranular fracture and microscopic plastic deformation

    研究表明：電場時效可在一定程度上提高1420合金的延伸率，但對強度則基本沒有影響；同時，電場時效減少沿晶分層斷裂比例，增加穿晶斷裂及微區塑性變形。
  11. From an examination of the tensile behavior of cz ly12 alloys under different temperature and strain rate, two kinds of deformation and intergranular fracture behaviors were observed that were opposite to the characteristic strain rate range in fine - grained superplasticity. the mechanisms are described as follows. the high ductility achieved at high strain rate is generally attributed to the dominant role of gbs accommodating mechanisms, which is considered as dislocation creep within grains controlled by subgrains

    研究選用自然時效淬火態的ly12鋁合金，進行了一系列不同溫度和應變速率下的單軸拉伸試驗， 480下，觀察到與傳統細晶超塑性特徵區間相反的行為：較高應變速率下，動態再結晶使晶粒細化，促進了晶界滑移，亞晶界控制的晶內位錯蠕變是晶界滑移的主要協調機制。
