实验证明:挤压铸造中的比压增加时,孕育铸铁件的细片状石墨向蠕虫状石墨转化的趋势加大,挤压铸铁件的抗拉强度和延伸率均有较大的提高。
The experimental results show that when the specific pressure in squeeze casting increases, the tendency of fine flake graphite in cast iron to convert into worm-like graphite increases. The tensile strength and elongation of extruded cast iron have been greatly improved.
