Description
Summary:	This study analyzes the effects of cold deformation and recrystallization on the microstructure, texture evolution, and mechanical properties of Ti–30Nb–4Sn alloy. The samples are cold rolled to reduce their thickness by up to 85%. The most deformed sample is subjected to recrystallization treatment. The crystallographic texture is determined by X‐ray pole figures. The 51% deformed sample shows a {203} texture. The 85% deformed sample shows two texture components: {203} and {130}<‐310>, while the recrystallized sample shows a fiber texture with the {130} plane parallel to the sample surface. Hardness increases and Young's modulus tends to decrease in response to increasing deformation. The recrystallized sample shows low hardness and Young's modulus. This study analyzes the development of texture in cold rolled and recrystallized Ti–30Nb–4Sn alloy. Cold rolling promotes an increase in hardness and a decrease in Young's modulus. The decrease in Young's modulus with plastic deformation and the low Young's modulus of the recrystallized sample are associated with the development of texture.
