摘　　要：为研究孕育处理对铸件组织和性能的影响情况,采用不同孕育处理方式制备厚大断面球墨铸铁试样。结果表明,多次孕育处理有助于改善厚大断面球墨铸铁的石墨形态、提高铸件力学性能。Some heavy section nodular iron test blocks were prepared by using different inoculation processes to investigate the influence of inoculation treatment on the structure and properties of castings. The resuh showed that the multiple inoculations were helpful to improve the graphite morphology and increase properties of the heavy section nodular iron castings.
