Abstract

Splat-cooled foils of a carburised high purity Fe-C alloy have been examined by transmission electron microscopy. The crystalline phases that arose with an Fe¯4.3 wt % C amorphous phase on quenching and those that nucleated from the amorphous phase on heating were identified. The former was the HCP solid solutionε-phase whereas the latter, termed MS-I and MS-II, developed via two independent reactions yielding single phase ferrite grains and generally ferrite plus cementite grains, respectively. These observations have been interpreted in terms of the relative dispositions of transformation curves of the various metastable crystallization products.
