| Abstract: | Al 98-3x Cu 2x Fe x Ni 1Ce 0.5 Zr 0.5 alloys have been prepared by means of spray forming technique and the influence of the content of Cu and Fe on the microstructures, mechanical properties and fracture mechanism has been investigated. Observation results showed that the Al 7Cu 2Fe phase can be avoided by keeping x <2 for spray formed Al 98-3x Cu 2x Fe x Ni 1Ce 0.5 Zr 0.5 alloys; the x= 1.5 alloy possesses the better mechanical properties with ultimate strength of 643 MPa, yield strength of 558.4 MPa, elongation of 8.4% and elastic modulus of 80.4 GPa. |
