用铁的熔化热校正铁碳相图固相线及H点的研究

Correction of Solid us and Point H in the Fe-C Binary Phase Diagram by Using the Melting Heat of Iron

根据铁的熔化热数据，校正了铁碳二元相图富铁端的固相线，并根据校正后的固相线，求出Ｈ点的碳含量为０．０６４％，结晶时碳在固、液相中的分配比为０．１２。

According to the data of the melting heat of iron, the author corrected the solidus of FeC binary phase diagram in the rich iron end,and according to the corrected solidus e-valuated the carbon content at point H in 0.06 4%,the distribution ratio of carbon content in solid and liquid phasc is 0.12。
