本文对JC及LSI引线用材料Cu-10％Fe-0.1％P合金的性能和强化机理进行了系统的研究。得出Cu-Fe合金在特定的冷热加工条件下可得到被高强度Fe相(α相)纤维强化的双相复合材料,它具有较高导电性和很高的机械强度,其强度与杨氏模量符合纤维强化复合材料的复合规则,并且观察到了纤维强化金属复合材料特有的四阶段形变过程,从而证实了此材料的强化是纤维强化复合效应所致。
In this paper, the properties and strengthening mechanisms of Cu-10% Fe-0.1% P alloy for lead and lead of JC and LSI are systematically studied. The results show that the Cu-Fe alloy can be obtained under the specific hot and cold processing conditions by the high-strength Fe phase (α phase) fiber reinforced dual-phase composite material, which has high electrical conductivity and high mechanical strength, and its strength and Young The Young’s Modulus is in accordance with the composite rule of the fiber-reinforced composite material, and the four-stage deformation process characteristic of the fiber-reinforced metal composite material was observed. This confirms that the strengthening of this material is due to the fiber-reinforced composite effect.
