304l stainless steel phase diagram

Ferrite normally does not form in 304L stainless steel without subzero temperature treatment or severe deformation below about 80&176;C even though the bcc phase is calculated to be stable to approximately 340&176;C.The phases obtained suggest that sputter-deposition can be used to determine the low temperature regions of phase diagrams.
