The results shows that the main reason of stainless steel pipe cracking is that intercrystalline corrosion result in creep rupture. 结果表明,不锈钢管鼓包状开裂的主要原因是晶间腐蚀导致的蠕变断裂。
The main fracture way of boron carbide-lanthanum boride composite material is intercrystalline rupture, while the transcrystalline rupture is minor, which is in accordance with fracture mechanism of boron carbide. B4C-LaB6材料断裂方式主要是以沿晶断裂为主,穿晶断裂所占的比例变得很小,这与陶瓷材料断裂韧性提高机制相一致。
