Description 234-239
A time-temperature-transformation (TTT) diagram has been constructed using dilation results. The phase transformations
have been confirmed through microstructural changes of AISI 1010 steel. The strength of this steel has been improved for
various applications using heat treatments. Experiments for a series of steel samples have been conducted between 310-
730°C isothermal temperature range using a thermo-mechanical simulator Gleeble®3800. The austenitised microstructure of
the steel has been transformed into a combination of ferrite, pearlite, widmanstätten ferrite, massive ferrite, upper and lower
bainite, and martensite, etc., when held at different isothermal temperatures. Ferrite along with pearlite have been observed
at higher isothermal temperatures while bainite with martensite have been observed at lower isothermal temperatures. Two
C-curves have been observed in pearlite and bainite transformation regions.
