摘要：

通过实验研究了采用新型蠕化剂情况下蠕墨铸铁的石墨形态、化学成分和力学性能。实验结果表明,最佳的蠕墨铸铁残余镁的质量分数为0.015%～0.022%,残余稀土的质量分数为0.068%～0.098%,该条件下蠕化率能达到50%～80%。研究结果为柴油发动机缸体的稳定生产奠定了理论基础。

Abstract:

This paper researched the graphite morphology, the chemical component and mechanical properties of compacted graphite irons by crushing new vermicular agent into the special ladle. The results indicate that 0.015%～0.022%Mg and 0.068%～0.098%Re are the optimal choice to obtaining 50%～80% vermicular graphite for the compacted graphite irons, which will provide theoretical principle to the steady product of compacted graphite irons.
