通过金相分析、拉伸断口形貌及能谱分析,发现00Cr13Ni6MoNb锻件开裂原因为粒状第二相晶界偏聚,使晶界弱化,引起沿晶脆性断裂。
通過金相分析、拉伸斷口形貌及能譜分析,髮現00Cr13Ni6MoNb鍛件開裂原因為粒狀第二相晶界偏聚,使晶界弱化,引起沿晶脆性斷裂。

By means of metallurgical analysis , tensile fracture morphology and energy spectrum analysis , the rea-son of forging cracking is granular secondary phase grain boundary segregation , which make grain boundary weaken and cause intergranular brittle fracture .
