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. (AU)
