摘要：
Two grades of the Nb-microalloyed steel, one modified with B, were subjected toin situ melting and the thermal schedules experienced by the billet surface in the continuous casting process. The hot ductility was evaluated at various temperatures at the straightening stage of the process. It was found that addition of B improves the hot ductility in the austenite region. Such improvement could be due to fast precipitation at grain boundaries as well as depletion of precipitants and strengthening elements in the matrix.
