高强度低应力铸铁及其形成机理的研究

Study on IIigh—strength and Low—stress Gray Iron and Its Formation Mechanism

本文从理论上阐述了高强度低应力铸铁的存在,对经典强度应力理论进行了修正,进而推断了高强度低应力铸铁的形成机理,同时通过试验数据对上述各过程进行了验证。

This article has discussed in principle the exist of the hlgh—strength and low—stress gray iron and modified the classical formula on strength and stress. Further more the forming mechanism of the highstrength and low—stress gray iron has been established. In this article, a numble of experiment datas have been given to support the conclusions discussed in the article.
