1) intergranular cracking
晶间开裂
2) intergranular corrosion cracking
晶间腐蚀开裂
1.
The results showed that above cracks are intergranular corrosion cracking basically in weak oxidative medium;they are caused by following factors mainly: contain some acetic acid and little formic acid in active medium,IGCC-resistance of shell material is insufficient,improper welding technology lead to local HAZ in the sensitized temperature range(450～850 ℃)for longer time.
结果表明,裂纹基本属于弱氧化性介质条件下的晶间腐蚀开裂;介质中含有一定量的乙酸(CH3COOH)和少量甲酸(HCOOH),塔体材料抗晶间腐蚀性能不足,不适当的焊接工艺导致部分热影响区较长时间处于敏化温度(450~850℃)范围是引发塔体开裂的主要因素。
3) Intergranular stress corrosion cracking
晶间应力腐蚀开裂
4) corrosion crack
腐蚀裂纹，应力腐蚀裂纹;晶间开裂
5) intergranular crack
沿晶开裂
1.
The reinforced connector of the down tail tube in hydrogen manufacturing converted furnace was intergranular crack.
制氢转化炉下尾管加强接头发生沿晶开裂,对接头的化学成分、断口形貌、显微组织等进行了检测与分析。
2.
Along with the diversification of components,the propagation form of cracks changes from intergranular crack into transcry.
Ti/Al2O3界面处生成的Ti3Al相以及Ti3Al周围的气孔是热疲劳裂纹的主要萌生和扩展地;随着成分的变化,裂纹的扩展由沿晶开裂转变为穿晶断裂,裂纹扩展的路线并不是直线,在各梯度层间发生了裂纹的偏转。

结果表明,造成主蒸汽滤网开裂的主要原因是晶界高温氧化,断口呈典型的沿晶开裂特征。
补充资料：晶间开裂
分子式：
CAS号：
性质： 金属材料破裂的金属学特征之一，裂纹沿晶粒之间的界面扩展。表征材料发生了脆性断裂，断口微观特征为“冰糖”状、岩石状。在材料的低温脆断、应力腐蚀破裂和氢脆破裂中经常能观察到晶间开裂。
