摘要: GH4169机匣环件在成形过程中需要反复加热到较高温度,从而导致晶粒粗化。通过已建立的GH4169高温合金析出相演变模型和晶粒长大模型模拟机匣环件热成形过程,并制定了加热规范。计算和试验结果表明,所制定的加热规范能够明显抑制机匣环件在制坯和轧制过程中的晶粒长大。

Abstract: GH4169 casing ring has to be repeatedly heated to a high temperature during the forming process, which results in grain coarsening. Based on the established phase evolution model and grain growth model of GH4169 superalloy, the heating processes for hot forming of the casing ring were formulated. The results of calculations and experiments show that the established heating processes can significantly hinder the grain growth of the casing ring during the blank making and rolling process.

Key words: GH4169 case ring, thermoforming, heating specification
