Description
Summary:Direct observation of the austenite-ferrite transformation is commonly assumed to be a quite complicated experimental problem. We have designed an original high-temperature extension for an analytical microscope iported from WENTWORT. The use of the extension and the method of differential-interference contrast makes it possible to study the dynamics of the transformation under various cooling regimes. We have observed the austenite-ferrite transformation in specimens of steel 15ps at 600-1000 deg C. The results allow us to assume that there exist two alternative mechanisms of the transformation that differ, in particular, in the length of the incubation period.
