The results show that the main reason is many little cracks(white spot) exist,and heavy reticulation structure,inclusion,coarse grain and side decarburized stucture.
结果表明,其发生断裂的主要原因是存在较多的小发纹(白点),加之较严重网状组织、夹杂物、晶粒粗大和边部脱碳组织,在机械加工力的共同作用下,导致轻轨发生断裂。

This paper introduces the effect of coarse grains on the ultrasonic inspection of 40CrMo steel used for crankshaft.
由于42C rM o曲轴锻造坯组织晶粒粗大,影响了钢中缺陷的超声波定性探伤效果。
3.
This paper introduces the effect of coarse grains on the ultrasonic inspect ion of 42CrMo steel used for crankshaft.
由于42CrMo曲轴锻造坯组织晶粒粗大,影响了钢中缺陷的超声波定性探伤效果。
4) coarse grain
粗大晶粒
1.
The effects of cold rolling processes on coarse grains of aluminium foil blanks in annealing are studied.
试验研究了变形程度、道次加工率、润滑等对铝箔坯料退火产生粗大晶粒的影响。
2.
The coarse grain in cast strip is produced on the condition that cool speed is not fast enough to overcool aluminum melt in whole cast area, and only provide proper temprature gradiant to keep cellular grain growing up.
铸轧区内铝液与铸轧辊接触瞬间，当铸轧辊冷却强度不足以使整个断面铝液同时产生较大的过冷，而仅能保持胞状晶生长所需的液体温度梯度时，铸轧板就会出现粗大晶粒；根据传热学原理，分析了具体生产条件，提出增大铸轧辊冷却强度、降低前箱温度以及添加铝钛硼丝等防止铸轧板产生粗大晶粒的措施。
3.
The paper is to solve the problem of the coarse grain occurred in the recrystallization annealing process of the 3003 aluminum alloy sheet.
为了解决3003铝合金冷轧板进行再结晶退火时出现粗大晶粒的问题,利用光学显微镜观察在同一温度下退火,随着保温时间的延长3003铝合金板组织的变化情况,确定了3003铝合金板的最佳退火保温时间。
5) particle coarsening
粒子粗化
6) coarse coal
粗粒子
1.
It is very difficult for making CWM from coarse coal although with high concentration.
通过实验室试验得出:粗粒子难以成浆,即使在较高浓度下,其粘度远远超于应用要求,且其稳定性、流动性极差,不能满足应用要求;组成煤浆的粒子平均粒径越大,粒度分布越窄,其成浆性越差。
