通过单向凝固，成功地制取了规则纤维排列的Ｆｅ－Ｃ－Ｃｒ共晶复合材料。研究了凝固速度对材料组织和性能的影响。研究表明，随着凝固速度（Ｒ）的增加，纤维间距减小，规整性变差，而材料的抗拉强度则呈抛物线变化，当Ｒ＝５０ｍｍ／ｈ时，可达２３００ＭＰａ。提出了该共晶合金在单向凝固过程中碳化物增强纤维的生长模型。 Through unidirectional solidification, the Fe-C-Cr eutectic composite with regular fiber arrangement was successfully prepared. The effect of solidification rate on the microstructure and properties was investigated. The results show that as the solidification rate (R) increases, the fiber spacing decreases and the regularity deteriorates, while the tensile strength of the material changes parabolically. When R = 50mm / h, it can reach 2300MPa. The carbide growth model of the eutectic alloy during unidirectional solidification was proposed.
