of Science and Technology,Tehran 4513863833,Iran摘 要:This work evaluated the isothermal transformation of austenite in unalloyed pearlitic ductile iron and drew the isothermal phase diagram of austenitization in the ductile iron. Austenite forms at grain boundaries and then grows up to graphite regions during austenitiza-tion. The formation kinetics......
