Abstract

Dual phase structures were produced in a C–Si–Mn–V steel from both ferrite-pearlite and martensitic structures by intercritical annealing at 750℃ and 810℃. Samples with different distributions of ferrite and martensite were cold rolled 60% and then recrystallized at 650℃ and 800℃ for different lengths of time. Texture measurements were carried out on the cold rolled as well as recrystallized materials using both the conventional pole-figure and ODF (Orientation Distribution Function) methods. The results indicated the presence of a reasonably strong 111 ∥ ND fibre in the cold deformed alloy. The textures in the recrystallized condition were found to be basically similar to the ones for the corresponding cold deformed materials, with the difference that the pole densities were somewhat weaker in the former. A weak {11,11,4} fibre and a weak and incomplete {337} fibre have also been observed in both the cold deformed and recrystallized materials. Samples recrystallized at the lower temperature of 650℃ exhibited a sharper {111} texture as compared to the 800℃ annealed materials and this difference in texture intensities were perceptibly reflected in the corresponding r-values.
