Full TextAbstract
In this research, graphitization transformation of commercial hypereutectoid steel called ck 100 was studied by the dilatometric experiments at the range of 600 – 700 ℃ from prior martensitic structure. Also the effect of quenching media on the initial graphitization time and completion of transformation has been discussed. Also, graphitization transition from the different prior microstructure was studied using microscopic observation. Analyzing dilatometric data acquisition confirmed good following results from Johnson-Mehli-Avarami equation. By calculating Avarami exponent, following if transformation kinetic from diffusion controlled nucleation and growth was resulted. Also, the minimum time for completion graphitization transformation was concluded about 45 hrs relative to the water quenched specimen after annealing at 670 ⁰C.
