  1. Based on these experiments, it may be claimed that there is segregation of sn to grain boundaries in 0. 15 % c steel during cooling from a high solution treatment temperature. this segregation reduces grain boundary cohesion, which results in low hot ductility and intergranular fracture

    通過試驗和計算得出: sn在0 . 1swt . % c鋼中發生非平衡晶界偏聚的臨界時間為1245左右，臨界冷卻速率大約為8 / s ，與試驗結果基本一致。
  2. The grain boundary fracture behavior in ni - base bicrystals

    鎳基雙晶體晶界斷裂特性研究
  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。
  4. With carbon content increasing, the carbide network on the fertile grain boundary sprouting and propagating. the fracture mode has been changed from cleavage to along boundary and the intergranular corrosion induced by solution chromium decreasing

    隨碳含量提高，晶界上碳化物萌發、擴展呈網狀，鑄件脆斷由解理斷裂發展為沿晶斷裂，同時鐵素體不銹鋼晶間腐蝕傾向增大。
  5. 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
  6. 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。
  7. Under the tensile stress, the fracture mode of za27 alloyed with si or mn is a mix type fracture - the plastic fracture and the brittle fracture are coexistence. cracks are mainly stemmed from brittle phases of si and mn and develop along the grain boundary

    適宜的加錳量為0 . 4 - 0 . 8 ；在拉伸應力作用下加入si或mn后的za27 ，合金的斷裂均為混合型斷裂，既有塑性斷裂，也有脆性斷裂。
  8. Toughening mechanism of zro2 ( y2o3 ) to alumina ceramic came from the phase change of t - zro2 on the grain boundary. with the content augmentation of zro2 ( y2o3 ), the fracture toughness of the alu

    Mga12o ;和zro :平均熱膨脹系數與a1203的熱膨脹系數比較接近，匹配性較好，不會產生明顯的熱應力，有利於氧化鋁陶瓷力學強度的提高。
