摘要
介绍了2024合金的用途、传统热处理工艺制度及其相构成,通过对样品的固溶、时效优化处理找到最佳的含钪2024铝合金热处理工艺,最佳处理工艺为:固溶温度500℃、固溶时间为4小时、60℃水淬,预时效温度为130℃、时间为6小时,最终时效温度为190℃、时间为18小时。
The usage, traditional heal treatment process system and its phase composition were introduced. The optimum process is as follows: solid solution temperature is 500℃ for 4h, 60℃ water quenching, pre-aging temperature is 130℃ for 6h, the final aging temperature is 190℃ for 18h.
