In traditional industries, niobium plates are usually obtained by Unidirectional-Rolling. The niobium plates obtained by Unidirectional-Rolling often show strong unevenness in grain size and texture distribution, which leads to their use in modern industries. The above has certain limitations. In this experiment, 135° Clock-Rolling and Unidirectional-Rolling were used to obtain niobium plates, and the differences in the thickness direction of the niobium plates obtained under the two process conditions were studied. The results show that 135° Clock-Rolling can help reduce the texture gradient of the high-purity niobium sheet in the thickness direction. In addition, niobium plates with a higher degree of {001} preferred orientation can be obtained under the conditions of 135° Clock-Rolling process, and after recrystallization, they still have a strong {001} preferred orientation. This texture The dominance of niobium helps to obtain a more uniform niobium plate, which is confirmed by the microhardness curve, microscopic characterization of recrystallized structure, and semi-quantitative calculation results of storage energy in this experiment. It is also worth noting that compared to Unidirectional-Rolling, the niobium plate obtained under 135° Clock-Rolling has a smaller difference in the storage energy of {111} and {100} orientations in the thickness direction, and does not show a significant energy gradient. This also helps to optimize the uniformity of high-purity niobium.
