Abstract:

Ba sed upon the results obtained concerning. the A3 transformation of Fe-Ni alloys, some remarks on the transformation of austenite in carbon steel have been made, namely: (1) how the quantity of retained austenite in oil quenched specimen becomes greater than that in water quenched one, (2) what is an essential difference between the primary and secondary troostites, (3) on the cause of the irreversibility of the A3 transformation found in Fe-Ni alloys, and (4) martensite is a metastable α solid solution situating below the extension line of the solidus of A3 transfnrmation in the Fe-C diagram.
