Abstract
The results of studies of the influence of intercritical annealing parameters on the austenite formation and its stability in TRIP steel (0.41 % C, 1.52 % Mn and 1.22 % Si) were presented in the paper. Based on the results of a dilatometric analysis and metallographic investigation it was noted that the pearlite to austenite transformation does not occur at a constant temperature, which is referred to as Ac-1, but rather within certain - possible to determine - temperature range which is enclosed within Ac-1s and Ac-1f values. It was shown, that in order to achieve austenite with a high carbon content, it is required to perform its annealing at a temperature slightly higher than the temperature at which the pearlite to austenite transformation begins (Ac-1s). Dilatometric analyses of cooling curves confirmed these observations. It was noted that the austenite formed at a temperature of Ac-1s + 10 degrees C transforms into martensite at a much lower temperature (M-s) than austenite formed during annealing in two-phase (alpha + gamma) temperature range, i.e. between Ac-1f and Ac-3 temperatures. It was also found that the formed austenite was the more stable the shorter annealing time was applied. Based on the obtained results the isothermal time-temperature-austenitisation (IHT) diagram was developed.
