grain boundary stress的意思|示意

Meanwhile, the tip of precipitates along grain boundary becomes obtuse, the alloying elements are depleted in the region near the grain boundary and the stress corrosion resistance is bettered.

同时，晶界沉淀物的端部由尖锐变得圆钝，晶界临近区域中的合金元素贫化，使材料的应力腐蚀抗力提高。

It is found that the alloying elements segregation in grains and the grain boundary cleanliness control the yield stress value and the tough-strength properties of this material respectively.

发现材料的晶内偏析和奥氏体晶界洁净度分析控制钢的屈服强度和韧度。从而改变了此钢按细化晶粒度控制强韧性的工艺指导思想。

The main reason for cracking is liquid copper diffused into the austenite grain boundary and grain boundary embrittlement was caused, so the welded pipe cracked under stress.

开裂主要原因为液相铜扩散进入奥氏体晶界引起晶界脆化，在应力作用下引起焊管开裂。
