Abstract: The law and characteristics of 7Cr7Mo3V2Si steel under the condition of continuous heating have been studied systematically by using an advanced fully automatic transformation determining instrument called Formaster. An austenitic forming diagram showing the law and characteristics of the steel has been determined.The result has shown that the P→A transformation for the steel carries out in a wider temperature region Aclb-Acle.The dissolution of different alloy carbides begins at various temperature.In condition of continuous heating, it is difficult for austenite to become a uniform solid solution.
