摘要
研究了微量合金元素Al、固溶温度和固溶时间对GH3030高温合金室温综合力学性能的影响,结果表明,微量Al的添加极大地提高了合金的室温拉伸性能,但其添加量必须适中;当Al含量为0.15%时,合金可获得较好的综合性能。合金的综合力学性能对固溶温度和固溶时间较为敏感,最佳的固溶温度和固溶时间相应为1010℃和10min。
The effect of trace alloying element Al, temperature and time of solution treatment on the comprehensive mechanical properties of refractory alloy GH3030 was studied at room temperature. The results show that the addition of a moderate amount of aluminum greatly elevates tensile properties of the alloy at room temperature. The alloy with 0.15% Al will provide good comprehensive mechanical properties, which is sensitive to temperature and time of the solution treatment. The preferable solution treatment process for the alloy lies in heating at 1010 ℃for 10 min.
