Notes:
In this paper, the microstructure and mechanical properties of yttrium oxide dispersed90W-7Ni-3Fe alloy were studied. The 90W-7Ni-3Fe nano-crystalline composite powder dispersedwith Y2O3 addition was firstly fabricated by MA process, and then the powder was pressed andsintered at 1480℃ for 30 min. A fine-grained 90W-7Ni-3Fe alloy with high tensile strength andelongation properties was obtained, in which the tungsten grain size was 8-12μm, the maximumtensile strength was 1050 MPa and the elongation was 30%. The Influence of rare earth oxide Y2O3on the mechanical properties and microstructure characteristics is discussed in detail herein
