AbstractTensile tests of GH4169 alloy were performed at room temperature. Different fractions, distributions and shapes of delta phase was prepared by aging treated at 880 degrees C, 930 degrees C and 980 degrees C for 5 h or 10 h. The effect of delta phase on the mechanical properties of GH4169 alloy was investigated. The results show that 0.2% yield strength and ultimate tensile strength of GH4169 alloy increase by 61 MPa and 78 MPa respectively when the fraction of delta phase increases from 2.20% to 5.21%. Then, the ultimate tensile strength remains at 1 012 MPa even when the fraction of delta phase reaches 7.56%. The fraction effect of delta phase on the strength improvement of GH4169 alloy is more significant than morphology, and the critical fraction value is 5.21%. In addition, the elongation decreases by 14.1% when the fraction of delta phase increases from 2.20% to 7.56%. Excessive needle or short rod shaded delta phase is responsible for the reduction of elongation.
