1) intercrystalline fracture
晶间断裂,沿晶界断裂
2) intercrys-talline cracking
沿晶界断裂
4) 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.
It is pointed out that the change of the mode from intergranular fracture to intragranular fracture cannot act as the strengthening mechanism of the ceramic, it is the important reason why the tou ghness of the ceramic cannot be improved significantly.
综述和分析了纳米碳化硅颗粒强化氧化铝基陶瓷材料的强韧化机制,认为由沿晶断裂到穿晶断裂的断裂模式的改变不是使复相陶瓷材料强韧化的机制之一,而恰恰是其韧性得不到显著提高的重要原因,并由此提出了有关复相材料新的设计思路。
6) intergranular fracture
晶间断裂
1.
The intergranular fracture characteristics in nanocrystalline and ultra-fine polycrystalline metallic materials present intensive size effect and microstructure geometry effect.
提出了一种针对超细晶和纳米晶金属(主要是fcc金属)晶间断裂的微结构计算模型,即采用基于机制的应变梯度塑性(CMSG)理论描述晶粒内部材料塑性变形过程中的变形、强化和尺度效应;采用黏聚力界面模型来模拟晶界的滑移和分离现象,以及晶间裂纹的萌生和演化,直至晶间断裂导致的材料失效。
