The Austenite Solidus and Revised Iron-Carbon Diagram, Transactions of the metallurgical society of AIME, Vol.221 (1961), pp. 323-331.
Notes:
The austenite solidus of the iron-carbon system has been determined using a seriea of diffusion couples, each of which consisted of a specimen of austenite held in contact with a melt saturated with austenite. After the equilibrium distribution of carbon had been established by diffusion at a specific temperature, i.e. the austenite specimen had become austenite of the solidus composition, the diffusion couple was cooled, sectioned and analysed for carbon.
A revised iron-carbon temperature-composition is presented.
