Microstructures of Cr-0.70Cr-0.15 In alloy during the thermo-mechanical process were observed and the electrical conductivity and tensile strength were tested.The α matrix phase was surrounded by(α + Cr) eutectic discontinuously while indium(In) dissolved in the α matrix phase homogeneously.Typical microstructures after cold deformation were preserved after ageing at temperatures below 500 ℃,while a small amount of recrystallization structures were observed after aging at 550 ℃ for 60 min.The results showed...
