• This seems due to the grain boundary sliding and diffusion hindered by precipitation of intergranular carbides, so the nucleation and growth rate of crack or cavity are reduced.
  结果表明，晶界碳化物大大提高了合金断裂寿命与延性、这是由于晶界碳化物的析出阻碍了晶界滑移与扩散，从而降低了裂纹或空洞形核与生长速率。
• The results show that the combination effect of temperature and corrosive gas contributes to the intergranular corrosion, thereafter, leading to the occurrence of the crack of the pole thread.
  结果表明，极丝在温度和腐蚀性烟气的共同作用下，产生了晶间腐蚀，因而产生早期断裂。
• Intergranular cracking is visible at crack initiation stage and transgranular cracking is distinguished at crack propagation stage.
  起裂区为沿晶开裂，在裂纹扩展阶段，开裂以穿晶为主。
• The fracture surface appeared intergranular crack, due to the oxide formed during tensile test.
  拉伸过程中形成的氧化物夹杂成为裂纹源，断口表现为沿晶断裂。
• The propagation mode of Al-Zn-Mg-Cu alloys is a mixed pattern of intergranular and transgranular ones. The relationship between misorientation of adjacent grains and propagation of fatigue crack obeys the crystal deformation mechanism of crack tips.
  Al-Zn-Mg-Cu合金疲劳裂纹的扩展呈穿晶与沿晶混合的方式，相邻晶粒的晶粒结构与裂纹扩展之间的关系遵循于裂纹尖端的晶体塑性变形机制。
• The secondary pore is the main type of the reservoir pore space, mainly including intergranular dissolution pore, intragranular dissolution pore, ultra_large pore, micro_pore and structural crack.
  储集空间类型为次生孔隙型，主要有粒间溶孔、粒内溶孔及超大孔隙、微孔隙和构造裂隙几种类型。
• Fatigue damage model near threshold region(ⅱ) intergranular crack mechanism
  门槛区疲劳损伤模型（Ⅱ）&晶间裂纹机制
• The oxidation degree of grain boundaries and crack propagation are qualitatively analyzed based on crack density and percentage of intergranular crack.
  用裂纹密度和晶界裂纹的比例对晶界氧化的程度及裂纹扩展情况定性地加以分析。
