Excerpt from Electrical Resistance and Critical Ranges of Pure Iron Whether or not either or both of these critical ranges, A2 and A3, are to be considered an allotropic point will depend on the definition of allotropy, about which there does not yet appear to be agreement. The reversible thermal and electrical behavior at A2 appears to be somewhat similar to that of a pure substance at its melting point, while at A3 there is a progressive change with temperature of the electrical and thermal properties which are not reversible, the reaction taking place at a higher temperature on heating than on cooling. The A3 change is certainly associated with recrystallization, while no crystallographic change has as yet been found at A2, which is also the temperature associated with the abrupt, reversible change of iron from the ferro-magnetic to the para-magnetic states.
