摘要
研究了具有不同金相组织的ＱＴ４５０１０铸态球铁所对应的机械性能。研究表明，对ＱＴ４５０１０铸态球铁的机械性能影响最大的因素是球铁的石墨形态，并给出了球化级别———机械性能曲线。在一定的条件下，当ＱＴ４５０１０铸态球铁的石墨球化级别为１～４级时，其机械性能合格。
The mechanical properties of as cast QT450 10 ductile iron with different metallographic structures were investigated. The result shows that it is the graphite morphology of nodular iron that mostly influence the mechanical properties of as cast ductile iron. The curve of nodulizing grade mechanical properties is given as well. On a certain condition, when the nodulizing grade of graphite of as cast ductile iron is grade 1 to 4, its mechanical properties are qualified.
