【Abstract】 This paper deals with the influence of structural inheritance on the granular bainite shape and the properties of 12CrlMoV steel. The result shows that, 12CrlMoV steel obtains the stripe shape of granular bainite by heating non-equilbrium structure and cooling in oil,and the bainite islands arrange in the obvious direction. The granular bainite structure with inheritance character has higher strength and toughness,as well as excellent hot strength.更多还原
