我们在作中铝(含铝8—15％)耐热铸铁时,发现一个值得注意的现象,就是在一定条件下,石墨可以向铁铝碳化物转化,这与一般熟知的概念相违反。另外,中铝铸铁具有优良的高温性能,但它的常温性能与石墨化关系甚大。所以研究它的碳化物与石墨的相互转变具 When we made the heat-resisting cast iron with aluminum (8-15% aluminum), we found a noteworthy phenomenon that under certain conditions graphite can be transformed into iron-aluminum carbide, contrary to the well-known concept. In addition, the aluminum cast iron has excellent high temperature performance, but its very room temperature properties and graphitization. So study its carbide and graphite with each other
