Abstract:

Conclusions An alloy of Fe-1.51C-3.09Cr undergoes an austenite-martensite transformation at -14C. The lattice parameters of the austenite and martensite, the lattice orientation relationship, and the habit plane for this transformation were experimentally determined. An analysis of the crystallography on the basis the WechslerLieberman-Read Trans. AIME, 1971503, l953 and Bowles-Mackenzie Acta. Met. 2129, 138, 224, 1954 theories showed that the experimental quantities could not be accounted for completely by either theory. Better agreement may be possible by incorporating an anisotropic dilation into the austenite-martensite interface. This more general theory is under consideration at present. Author
