1) mixing fracture along and through the grain boundaries
沿晶/穿晶混合型断裂
3) 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。
4) transcrystalline fracture
穿晶断裂
5) transgranular fracture
穿晶断裂
1.
Scanning electron microscopy (SEM) observation indicated that the fracture mode of this nanocomposite is mainly transgranular fracture, and many grain pull outs existed on its fracture surface.
SEM观察表明,Al2O3/TiC纳米复合陶瓷刀具材料的断裂方式主要是穿晶断裂,材料的断口处存在大量的晶粒拔出。
2.
The fracture type of the pure molybdenum bar with good transverse ductility is mainly a transgranular fracture type and net-type, which is characterized by a large amount of cleavage planes and river patterns.
在此过程中,镦态纯钼棒中形成的位错胞亚结构逐渐合并形成许多细小亚晶;纯钼棒经锻造镦粗变形后断口以穿晶断裂为主,具有明显的河流状花样和解理台阶,解理面上出现大量塑性变形的撕裂岭,且形成鱼网状的韧窝。
3.
The fracture type of pure Mo is intergranular fracture,the enhancement of the crack propagation stress of the Mo-C alloy is due to the addition of carbon,which makes the fracture type change to a transgranular fracture type.
结果表明:1号Mo-C棒中C含量(摩尔分数)为290×10-6,O含量为25×10-6,2号Mo-C棒中C含量为150×10-6,O含量为25×10-6;在同样条件下,2号Mo-C棒的横向弯曲性能更好;2号Mo-C棒的再结晶温度为950～1100℃左右;随着退火温度的升高,合金的横向弯曲性能逐渐提高,在1100℃时,合金的横向弯曲伸长率最高,达到10%;纯钼的断裂方式以沿晶断裂为主,添加C后,合金的裂纹扩展应力得到提高,合金的断裂方式变成以穿晶断裂为主,断口上有大量的解理面,具有明显的河流状花样和解理台阶;当添加的C含量偏高时,合金中生成大颗粒的碳化物,这种大颗粒的碳化物降低了合金的塑性。
6) intercrys-talline cracking
沿晶界断裂
