研究了定向凝固Cu-Fe-Co合金的组织和性能。结果表明：在定向凝固条件下，可以获得分散良好的富铁纳米颗粒，其尺寸为5 ~ 50nm，铁纳米颗粒与铜基体之间具有相干界面；该Cu-Fe-Co合金具有优异的综合力学性能，抗拉强度可达294.35Mpa，伸长率为33.43%；富铁纳米颗粒提高了合金的抗拉强度，降低了塑性。
The microstructure and properties of Cu-Fe-Co alloy obtained by directional solidification were investigated. Results show that the finely dispersed iron-rich nanoparticles can be obtained under the directional solidification condition, with the size of 5-50nm and the coherent interface between the iron nanoparticle and the copper matrix. The Cu-Fe-Co alloy with excellent comprehensive mechanical properties, tensile strength up to 294.35Mpa, the elongation is 33.43%; Iron-rich nanoparticles increase the tensile strength of the alloy reduce the plasticity.
