一种解决GH4169合金混晶异常组织的热处理方法
摘要：
一种解决GH4169合金混晶异常组织的热处理方法，本发明涉及GH4169合金热处理领域。本发明要解决现有GH4169合金存在混晶异常组织的技术问题。热处理方法：将存在混晶异常组织的GH4169合金材料的固溶温度提高30～70℃，保持30～40min，然后进行油冷处理。本发明通过提高固溶温度，使材料发生充分静态再结晶，进而组织均匀化，晶粒度满足标准要求。本发明用于解决GH4169合金存在混晶异常组织。
摘要（英）：

The invention relates to the field of GH4169 alloy thermal treatment, and provides a thermal treatment method for solving an abnormal mixed-crystal structure of a GH4169 alloy to overcome a technicalproblem that GH4169 alloys at present have abnormal mixed-crystal structures. The method includes increasing solution treatment temperature of the GH4169 alloy material having an abnormal mixed-crystal structure by 30-70 DEG C, maintaining the temperature for 30-40 min, and then performing oil cooling treatment. Through increasing solution treatment temperature, the material is subjected to sufficient static recrystallization so that the structure becomes uniform and the crystal grain size meets a standard requirement. The method is used for overcoming a problem that GH4169 alloys have abnormal mixed-crystal structures.
