采用JMatPro软件对Haynes282合金进行热力学计算，得到温度由1 400℃降至600℃时合金内不同析出相的含量，分析了铬、钴、钼、钛、铝、碳、硼等元素含量对析出相析出行为的影响。结果表明：碳化物的析出量主要由碳含量决定；铬元素可以增强M₂₃C₆的稳定性；铬、钴、钼、钛、铝能促进σ相的析出及稳定；钼含量增加可以促进μ相的析出，而硼、钴、铬、钛、铝等元素会抑制μ相的析出；硼元素对M₃B₂的稳定性没有影响，但含量增加会增大其析出量；钛元素能促进γ'相的析出并增强其稳定性，铝元素可增加γ'相的析出量。

Thermodynamic calculation was conducted on Haynes282 alloy by using JMatPro software, and then the content of different precipitates in the alloy from 1 400℃ to 600℃ was obtained. The effects of chromium, cobalt, molybdenum, titanium, aluminum, carbon and boron on the precipitate behavior of precipitates were analyzed. The results show that the precipitate amount of carbides was mainly determined by carbon content. Chromium could enhance the stability of M₂₃C₆. Chromium, cobalt, molybdenum, titanium and aluminum could promote the precipitation and stability of σ phase. The increase of molybdenum content could promote the precipitation of μ phase, while boron, cobalt, chromium, titanium and aluminum inhibited the precipitation of μ phase. Boron had no effect on the stability of M₃B₂, but the increase of content improved the precipitate amount. Titanium contributed to the precipitation and stability of γ' phase, and aluminum improved the precipitate amount of γ' phase.
