摘要：
The austenite transformation characteristics for various warm-rolled pearlite during rapid heating were investigated. The results indicate that the start temperature (T-s) is sensitive to the microstructural feature of pearlite whereas the dislocation plays an important role in the transformation rate; at the same time. the uniformity,of austenite grains is more or less affected by the amount of spheroidized pearlite. A critical effect on the state of austenite grain is created through the influence of initial microstructures on the start temperature of transformation.
