With copper powder, aluminum powder, nickel powder and 匡威1970s水蜜桃色官方-免费-完整版片 powder as raw materials, Cu-10Al-4Ni alloys containing different mass fractions (0, 1.6%, 3.2%, 4.8%, 6.4%) of iron were prepared by powder metallurgy process. The effect of iron content on the 匡威1970s水蜜桃色官方-免费-完整版片 and properties of the alloy was studied. The results show that the 匡威1970s水蜜桃色官方-免费-完整版片 of the alloy without iron addition consisted of ΚⅢ
phase, α phase and Al4Cu9
phase. When the mass fraction of iron was 1.6%, the ΚⅢ
phase increased and Al4Cu9
phase decreased in the alloy. When the mass fraction of iron was 3.2%, Al4Cu9
phase further decreased, and ΚⅠ
and ΚⅡ
phases were precipitated in the alloy. When the iron content continued to increase, the Al4Cu9
phase disappeared, ΚⅠ
phase increased while ΚⅢ
phase decreased. With increasing iron content, the sintered density of the alloy decreased, the hardness decreased first then increased and then decreased, and reached the maximum with iron mass fraction of 3.2%. The 匡威1970s水蜜桃色官方-免费-完整版片of the alloy fluctuated with increasing iron content, and reached the maximum when the mass fraction of iron was 4.8%.
