Abstract
The present study aims the modelling, elaboration and implementation of a computational algorithm to calculate the bidimensional and transient temperature distribution using rectangular coordinates in order to analyze the microstructural comportment of the carbon steel ABNT 1025. The heat conduction equation is spatially discretized by the Finite Differences Method and the Explicit Method was used to discretize time. Using MATLAB as software, the matricial solution of the linear systems were done by the Jacobis method. Initially, many tests were done in order to verify the computational mesh and time-step independency and secondly how the temperature field works for two different states of cooling. By the end, it is verified by the cooling curves compared with the steel Isothermal Time Transformation (ITT), which microstructural phase is formed. It is important to affirm that these results are extremely important to the confiability of the steels microstructures.
