WebJun 7, 2024 · In this regard, in situ observations were made on σ phase formation and dissolution in a 2205 duplex stainless steel using synchrotron X-Ray diffraction [36,37] and it was reported that σ phase precipitates rapidly in the initial stages of heating, dissolves as the temperature increases and is reformed on cooling, the dissolution temperature of σ … WebThe sigma phase, which is a very brittle and harmful phase in stainless steel, is formed within these temperature ranges, for example from around 500 to 800 degrees Celsius. So, avoiding this sigma phase is very important. And also, this sigma phase is decomposed into an iron rich phase and chromium rich alpha prime phase.
