NODULARIZATION OF EUTECTIC IN AUSTENITE-BAINITE STEEL
奥氏体—贝氏体抗磨钢中共晶体的团球化

Nodularization of eutectic in austenite-bainite steel modified by Mg and Al have been investigated by means of TEM,SEM and EPMA.Results show that the nodular eutectic is pseudo-eutectic of austenite and Fe3C, which is formed between austenite dendrites at
