铬铸态珠光体球铁的研究

Investigation on Chromium As-cast Pearlite Nodular Cast Iron

研究表明,将铬作为铸态珠光体球铁的合金元素,只要成分匹配合理,处理工艺得当,可获得较高的强韧性;已浇注了曲轴、摇臂等铸件。

Investigation has showed that fairly high strength and toughness could be reached by using chromium as alloying element of as-cast pearlite nodular cast iron so long as the composition matching was rational and treatment process was proper. Some castings, such as crankshaft, rocker arm et al were produced.
