石墨球 meaning in Chinese
graphite nodule
graphite pebbles
Examples
- These graphite spheroids are know as “ crack arresters ” in the ductile iron industry because of their ability to stop cracks in their tracks
在球墨铸铁行业内，这些石墨球称为“裂缝终结者” ，因为它们具有阻止断裂的能力。 - The low - enriched uranium fuel consists of half - millimetre - sized particles of uranium dioxide encased in graphite and silicon carbide , which in turn is encased in a graphite ball
低浓缩的铀燃料为包裹在石墨和碳化硅中半毫米大小的二氧化铀微粒，石墨和碳化硅则被包裹在石墨球中。 - 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。 - In order to avoid eutectic carbide , improve nodularity , increase nodule count and increase mechanical properties , three times of inoculations were adopted in the centrifugally cast nodular iron pipes production : a ) inoculation in ladle ; 2 ) pouring stream inoculation ; 3 ) in - mold inoculation
摘要在离心铸造球墨铸铁管生产中，为防止共晶渗碳体析出，改善球化，增加石墨球数，提高力学性能，采用了三次孕育： ( 1 )包内孕育； ( 2 )浇注时随流孕育； ( 3 )型内孕育。 - 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。
