Abstract	Sono state esaminate le condizioni per il trattamento termico finale di alcuni fra gli acciai duplex di piu largo impiego. Dopo il mantenimento a temperature comprese fra 1050 e 1100°C, necessario per ripristinare il corretto rapporto fra austenite e ferrite e solubilizzare le eventuali fasi dannose, deve essere eseguito un raffreddamento sufficientemente rapido, per evitare che queste possano riprecipitare. I tempi di precipitazione delle fasi ? e ? nell'intervallo critico di 750-950°C sono stati determinati con trattamenti isotermici e raffreddamenti a velocita controllata, che hanno consentito di determinare le velocita di raffreddamento minime necessarie per evitare la formazione di queste fasi.
