等温淬火时间对贝氏体球墨铸铁组织的影响

The Effect of Isothermal Quenching Time on Bainite Spheroidal - Graphite Cast Iron

本文研究了等温时间对球铁上贝氏体组织的影响,确定了等温时间和上贝氏体的关系,测定了相应组织的硬度,为进一步制定等温淬火制度提供了可靠依据。

In this paper, the effect of isothermal time on the structure of upper bainite of spherical iron has been studied, the relationship between isothermal time and upper bainite has been determined , the hardness of correspodent structure has been also measured, which further provide reliability for making isothermal quenching procedure.
