Abstract Scope |
The computation of calculation of austenite fraction and its carbon content has been performed using Newton's method that minimizes error between calculated percentage change in length and experimentally recorded percentage change in length at each temperature step up to temperature above Ac3 from dilatation data obtained on heating Fe-0.2C-5Mn-0.8Si-0.4Al medium Mn steel having initial retained austenite in martensitic micro structure for different heating rate 1,25 and 50 degree Celsius per second. The simulated change in pct. length is approximated as one third of the pct. change in volume, where volume at any temperature is proportional to sum of multiplication of mole fraction of phase and unit volume in that phase considering both mole fraction of phases and its unit volume can change with temperature. |
