An investigation of the iron-carbon constitutional diagram, part I-preliminary survey of the delta ferrite region, Journal of the Iron and Steel Institute, Vol 135 91937), pp.281-292.
Notes:
A portion of the iron-carbon constitutional diagram, falling within the composition limits of 0.003 to 1.01% of carbon and an approximate temperature range of 1550-1300 C, is defined. The diagram is based on the results of thermal curves taken on 24 alloys prepared from high-purity materials.
