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) intergranular cracking
沿晶开裂
1.
The results show that the main reason for the cracking was high temperature intergranular oxidation,with the fracture morphology being a typical intergranular cracking character.
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。
3) IGSCC
沿晶应力腐蚀开裂
1.
However,laboratory tests and field experience indicates the 13 Cr steel undergoes inter-granular stress corrosion cracking(IGSCC) in the heat affected zone of the welds.
但是实验室试验和现场经历表明,13Cr马氏体不锈钢焊接接头热影响区发生了沿晶应力腐蚀开裂(IGSCC)。
5) intergranular crack
沿晶裂纹
1.
The results show that working for long time under high temperature,the wall of reheater pipe is severely thinned with action of oxidation and erosion on the inside and outside surface,and the material of pipe becomes brittle and the intergranular crack forms.
结果表明,由于长时高温运行,再热器管在内外表面氧化腐蚀作用下,管壁严重减薄,材料组织脆化,形成沿晶裂纹,管子不足以承受管内蒸汽压力,形成脆性开裂爆口。
2.
The intergranular cracks found in transition zone were also analyzed and some advices were put forward.
结果表明,两起事故都是由叶片激光熔覆层中缺陷引起的疲劳断裂,同时还分析了过渡区附近的沿晶裂纹产生原因,并提出了一些建议。
6) intergranular fracture
沿晶断裂
1.
The results indicated that the fracture toughness reduces and the tendency to intergranular fracture increases with both reducing temperature and raising loading rate,which shows the low temperature effect and high loading rate effect and both of them promot each other.
焊缝金属沿晶脆性断裂是特定的材料因素、结构因素和环境因素共同作用的结果,沿晶脆性断裂倾向决定于晶界协调相邻晶粒塑性变形的能力,在晶界不足以协调其两侧晶粒的变形时便出现沿晶断裂。
2.
The results show that intergranular fracture prevails as quench rates decrease for the alloy with Zr<0.
1%合金随着淬火速率的降低,由穿晶破断和沿晶开裂的混合型断裂逐渐转变成沿晶断裂;其主要原因是淬火速率降低使晶界无沉淀析出带(PFZ)宽化。
3.
