Effects of Mo-C dipole on the development of recrystallization texture are discussed in 0.03mass% carbon steels containing 0.07 to 1.01mass% Mo. The hot-rolled steels were annealed at 973K and then cold-rolled 85% in reduction. Decarburized and cold rolled steels were also used. These steel sheets were annealed up to 973, 1023 and 1073K with two kinds of heating rate in argon gas and then quenched. The following results were obtained. (1) The development of γ-fiber in the early stage of recrystallization at 1023K is restrained in all the slow-heated carbon steels. But it is accelerated during grain growth up to 1073K in the carbon steels containing 0.51mass% Mo or more. (2) γ-fiber in all the carbon steels is not developed in quick-heating up to 1023K or 1073K. (3) γ-fiber in the decarburized steels which were slow-heated up to 1073K is developed regardless of molybdenum content. (4) Either the increase of Mo-C dipoles themselves or the decrease of single solute carbon atoms as a result of formation of dipoles may contribute to the development of γ-fiber during grain growth by slow-heating.
