Continuous Cooling Transformation Curve Cct Of Duplex Stainless Steel Continuous cooling transformation (cct) diagrams of two types of cast duplex stainless steels, cd3mn (fe 22cr 5ni mo n) and cd3mwcun (fe 25cr 7ni mo w cu n), in order to understand the time and temperature ranges for intermetallic phase formation. the alloys were heat treated isothermally or under controlled cooling conditions and then. 5 computational simulation of duplex stainless steel continuous cooling transformation curves using dictra® microstructural behaviours consistent with observed in literature 10,12,15,17,18 . The kinetics of continuous cooling transformation (cct) curves were calculated and experimentally validated from the computational time temperature transformation (ttt) curves using the additive rule. employing an implemented finite element analysis (fea) thermal model, a cooling rate limit for a three layered multipass weld was determined. The kinetics of brittle phase transformation in cast duplex stainless steels cd3mn and cd3mwcun was investigated under continuous cooling conditions. cooling rates slower than 5 °c min. were obtained using a conventional tube furnace with a programable controller. in order to obtain controlled high cooling rates, a furnace equipped to grow crystals by means of the bridgman method was used.
