Abstract The morphology of the phase and the grain size generally have a significant influence on the mechanical properties of the alloy. (Cu-30Fe)-2X alloys also significantly have been affected by the morphology and solidification process of the phase. Compared with the Cu-30Fe alloy, which has a dendritic Fe phase due to the separation of meta-stable liquid phases, the addition of Si causes the formation of a spherical Fe primary phase with a fine size, and enhancement of the volume fraction of the secondary separated Cu phase in the formed Fe phase and primary α-Fe phase. Moreover, it leads to an implement of yield strength that is about 35% greater than a Cu-30Fe alloy. The addition of Nb and V resulted in the formation of coarse Fe units, which resulted in a decrease in the yield strength due to the concentration of stress. These results will be used as useful data for industrial applications aimed at controlling microstructures and improving mechanical properties in alloy designs.

添加微量合金元素对(Cu-30Fe)-2X合金力学性能和显微组织微观演化的研究

摘要 相的形貌和晶粒尺寸通常对合金的力学性能有显着影响。(Cu-30Fe)-2X 合金也受到相的形态和凝固过程的显着影响。Cu-30Fe合金由于亚稳态液相的分离而具有枝状Fe相，与Cu-30Fe合金相比，Si的加入导致形成了细小的球形Fe初级相，并提高了Fe的体积分数。形成的 Fe 相和初级 α-Fe 相中的二次分离的 Cu 相。此外，它导致屈服强度比 Cu-30Fe 合金高约 35%。Nb和V的添加导致粗大Fe单元的形成，由于应力集中导致屈服强度降低。
