Notes:
Continuous cooling and isothermal dilatometry was performed for a binary Fe-0.3C alloyand a ternary Fe-0.3C-1.0Mn alloy at slow (〈 0.1 oC/s) cooling rates and isothermally at temperaturesbelow the equilibrium eutectoid reaction temperature but above the bainite start temperature (625 to715 oC). Some of the test conditions produced an unusual morphology in which fine scale‘sub-grains’ are decorated with carbide, with additional discrete carbide particles inside the‘sub-grains’. A detailed investigation into the network carbide formation indicates formation duringaustenite decomposition, as opposed to a post lamellar transformation coarsening or spheroidizationreaction, but only for select temperatures, and apparently only during isothermal conditions
