蠕虫状石墨铸铁的机械性能很接近球铁的性能,而导热性几乎与片状石墨铸铁一样。为了研究蠕虫状石墨的结晶条件,对以稀土孕育的铸铁试样在离子腐蚀前后,采用逐层磨削的方法,进行了研究(见表)。
The mechanical properties of vermicular graphite cast iron are very close to those of ductile iron, and the thermal conductivity is almost the same as that of flake graphite cast iron. In order to study the crystallization of vermicular graphite, a study was carried out on the samples of cast iron nurtured by rare earths before and after ion etching using layer-by-layer grinding (see table).
