Abstract
The martensite-start temperature (Ms) on cooling and the austenite-start temperature (As) on heating in the iron-nickel system have been determined between 9.5 and 33.2 atomic pet nickel. By considering the α and ψ phases to be regular solid solutions, it is shown that To, the temperature at which δFα→ψ = 0, lies approximately halfway between Ms and As. This relationship has been corroborated by a study of the effect of plastic deformation on Ms and As.
