【Abstract】 A review was made on recent investigations of ferrite-martensite dual phase steels. Emphasis was laid on the methods for obtaining duplex structures, mechanical properties of dual phase steels and affecting factors. Different viewpoints were concluded concerning phase transformations, deformation behavior and mechanisms of strengthening and toughening of these steels and discussions were made on several problems in this field.更多还原
