为了解决现代工程材料对灰铸铁的特殊要求,即高σb低HB或高HB低σb,利用热分析法及多参数解析展示图,揭示出共晶度、孕育程度与机械性能之间的综合规律.研究结果表明,根据机械零件的性能要求,参照灰铸铁综合规律,制定出相应的工艺措施和成分配比,零件的机械性能完全能够达到预期效果,因而灰铸铁零件的材料,可由以往的"选择"转向"设计"这个新的概念.

To fit the special needs of gray cast iron as a new engineering material,i.e.,higher σb and lower HB,or lower σb and higher HB,using the method of heat analyzing and polyparameters analytic figures,the synthetic rules of carbon saturation degree,inoculation degree and mechanical properties can be exposed.The result shows that,according to the needs of the part′s mechanical properties,referring to the synthetic rules of gray cast iron,the corresponding technological measure and composition proportion can be defined,by which we will get the exact mechanical properties that could achieve the result expected completely.Thus,the casting for gray cast iron might be "designed"from"selected".
