摘　　要：对GH4169合金进行近等温锻造试验,结果表明:近等温锻造GH4169合金微观组织和拉伸性能对温度场敏感高,对变形量和应变速率不敏感,有利于GH4169合金近等温加工成形。The near-isothermal forging experiment of GH4169 alloy is carried out. The results show that the microstructure and tensile properties have high sensitization to the temperature pattern, but low sensitization to the deformation and strain rate, which is benefit to the near-isothermal forming of GH4169 alloy.

关 键 词：近等温锻造 GH4169合金 拉伸性能间隙相
