Microstructure and properties of Cu-Fe alloy prepared by spray forming

Abstract

Abstract To prevent or reduce the issue of macroscopic segregation in metastable immiscible Cu-Fe alloys during solidification, the alloys were produced using spray forming technology and subsequently cold rolled. The Cu10Fe alloy microstructure characteristics were investigated, and its mechanical properties were evaluated and compared with those of cast alloys. The results show that the alloy produced by spray formed has a well-dispersed Fe phase and the grain size is smaller, which effectively suppresses macroscopic segregation. The mechanical properties of spray-formed Cu-Fe alloys are higher than those of cast alloys, and the tensile strength and elongation of the alloys after cold rolling are 584 MPa and 2.2% respectively. The study provides valuable insights into the optimization of spray deposition techniques for producing high quality Cu-Fe alloys.
