摘要/Abstract

摘要： 分析了时效温度、时效时间、固溶温度、铬和钼含量对2205双相不锈钢中σ相析出量的影响规律。结果表明:随着时效时间延长,σ相析出量依次增加。在相同的时效时间下,随着时效温度升高σ相含量依次增大,在850 ℃时达到最大值;温度超过850 ℃后,随着时效温度升高σ相含量依次减小。时效时间相同的情况下,随着固溶温度、铬含量和钼含量升高,σ相析出时间变短、析出量增加。

关键词: 2205双相不锈钢, 时效, σ相, 铬含量, 钼含量

Abstract: Effects of aging temperature, aging time, solution temperature, Mn and Mo content on the precipitation quantity of σ phase in 2205 duplex stainless steel were analyzed. The results show that with the aging time increasing, the precipitation amount of σ phase increases. At the same aging time, the content of σ phase increases with the increase of aging temperature. The precipitation quantity of σ phase is largest when aged at 850 ℃. When the temperature exceeds 850 ℃, the quantity of the σ phase decreases with temperature increasing. Increasing the solution temperature, Cr content and Mo content can make precipitation time shorten and the precipitation quantity increase at the same aging time.

Key words: 2205 duplex stainless steel, aging treatment, σ phase, Cr content, Mo content
