Texture development in cold deformed and recrystallized Ti–30Nb–4Sn alloy and its effects on hardness and young’s modulus

Abstract

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}<010> texture. The 85% deformed sample shows two texture components: {203}<010> 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.
