graphite nodule meaning in English
石墨球
Examples
- These modified graphite nodules provide ductile iron with physical properties greater than cast iron and comparable to steel
这种改进后的球体使得使得球墨铸铁比铸铁和钢相比具有更加优异的物理性能。 - The strength of extension of low carbon ductile cast iron can reach 750mpa in casting state , the impact ductility can reach 20j / cm2 . the diameter of graphite nodule is 5 - 20 ( am , the base body is consisted of pearlite -
低碳球铁在铸态下的抗拉强度可达750mpa ，冲击韧性可达20j cm ~ 2 ，其中石墨球直径在5 20 m ，基体以珠光体为主，有少量的铁素体与渗碳体。 - It is indicated that the improved model can calculate the fraction of ferrite and pearlite more accurately , and can specially reflect the effect of both undercooling during the eutectoid transformation and the amount of graphite nodules formed during the process of eutectic reaction on the fraction of pearlite
结果表明，改进的模型可以更准确地预测球铁中铁素体和珠光体的数量，能够准确地体现共析阶段过冷情况和共晶球墨数对珠光体数量的影响。 - A little ferrite and cementite , through the analysis of the strengther and ductiler , we draw the conclusion that this is very important in reality , observing the graphite nodule in sem and tem , there are many spheroiding element and anti - spheroiding elements in the core and edge of graphite nodule , they form the oxides sulphide and nitride . we draw the conclusion that they may be the core of graphite nodule
在扫描电镜( sem )与透射电镜( tem )上观察石墨球，与传统石墨球相比低碳球铁的石墨球呈细小点状分布，球墨中心聚集有较多的球化元素而在边缘处分布有反球化元素。石墨球中心存在有氧化摘要一物、硫化物以及氮化物等组成的复杂的化合物，经分析认为它们是球状石墨形核的有效核心。
