摘要(Abstract)：

采用光学显微镜(OM)和扫描电镜(SEM)研究了固溶温度、固溶时间及时效温度对不同冷轧变形量的GH4090合金扁丝显微组织和析出相演变的影响。结果表明：当变形量为60%,GH4090合金扁丝固溶后的晶粒最粗大，晶粒度在4.5级～5.5级，当变形量为68%,固溶后晶粒被细化，晶粒度在6.0级～7.5级；固溶时间对GH4090合金扁丝晶粒的影响最小，固溶时间从15 min延长至45 min,晶粒度基本不变；随着固溶温度的升高，组织逐渐粗化，退火孪晶数量减少，形状由宽变窄，由短变长；时效温度为550～600℃时，GH4090合金扁丝γ′相的尺寸小于20 nm,弥散分布于基体，M_(23)C_6次生碳化物析出温度为650℃,随着时效温度的升高，M_(23)C_6碳化物向晶界一侧长大，呈片层状分布。
