摘要：

以太原钢铁（集团）有限公司工业化生产的N06625镍基合金板材为研究对象，采用金相显微镜、扫描电镜、能谱分析等手段，对其组织性能开展了研究。结果表明：工业化生产的N06625镍基合金板材的轧制态析出物主要以条状的（Nb,Ti）（C,N）以及细小的MoNbC复合析出物为主；高强度等级N06625镍基合金板材的适宜热处理温度为1000 ℃左右，低强度等级N06625镍基合金板材的适宜热处理温度为1150 ℃左右；所生产的N06625镍基合金板材具有优异的冶金纯净度、力学性能及耐腐蚀性能，可为用户选材提供数据支撑。

For N06625 nickel-based alloy plate industrially produced by Taiyuan Iron and Steel Group Co., Ltd., its microstructure and properties were studied by metallographic microscope, scanning electron microscope, energy spectrum analysis and other methods. The results show that in the industrial production of N06625 nickel-based alloy plate, the rolled precipitates are mainly strip-shaped (Nb, Ti) (C, N) and fine MoNbC composite precipitates. The suitable heat treatment temperature of high-strength grade N06625 nickel-based alloy plate is about 1000 ℃, while that of low-strength grade plate is about 1150 ℃. The produced N06625 nickel-based alloy plate has excellent metallurgical purity, mechanical properties and corrosion resistance, providing data support for user to select materials.
