Tensile properties,stress rupture properties,creep properties and fatigue properties of alloy GH150 have been studied under service conditions for the high-pressure compressor blades.The results of the tensile tests show that both the tensile strength and the plastic properties keep stable from room-temperature to 600℃ and fall down obviously at 750℃.The creep rupture strength at 600℃ and 650℃,the limitation values of the axis tensile fatigue(under 107 cycle) and the limitation values of the rotating bending fatigue(under 107 cycle) obtained from this experiment show that alloy GH150 is with good combination properties.
