石墨化元素

影响焊缝成型的因素有两个：一是石墨化元素Al的加入量；二是焊缝中的碳含量。

There are two factors affecting the formation of weld beam : One is the added amount of the graphite element Al , and the other is the the content of carbon in the welding beam .

所有石墨化元素均降低介稳定共晶温度，而提高稳定共晶温度，并使两者间距扩大。

All graphitizing elements decrease the metastable eutectic temperature , increase the stable eutectic temperature and enlarge their distance .

铋是阻碍石墨化元素，在生产可锻铸铁件时常采用添加铋的办法来获得白口组织；

Bismuth is an anti graphitization element during producing malleable cast iron , it is applied to obtain white iron texture .

研究表明，球状石墨及促进石墨化元素有利于其热疲劳性能的提高，而碳化物及反石墨化元素则削弱其热疲劳性能。

The results showed that spheroidal graphites and graphitizing elements improve the thermal fatigue property obviously , while carbides and its promoting elements weaken the property .
