The nucleation site of austenite from pearlitic structure during reverse transformation at 1073 K in Fe-0.6C-1Cr (mass%) alloy was examined by means of electron backscattering diffraction. It was found that austenite preferentially nucleates at high-angle boundaries (HABs) of pearlitic ferrite. Some austenite nuclei maintain a near Kurdjumov-Sachs (K-S) orientation relationship (OR) with one or two pearlitic ferrites adjacent to the HAB. Austenite nucleated at the HAB face preferentially grows into the adjacent pearlitic ferrite, deviating greatly from the K-S OR.
