Relationship Between the Texture and Young’s modulus over the Section of Cold-rolled Rods of Low-modulus Biocompatible Alloy

Abstract

The influence of the texture type on the Young's modulus value in the different sections of cold-deformed rods of Zr-31Ti-18Nb alloy (IMP BAZALM) was studied. It was found, an increase in the compression deformation degree from 63 to 84 % of Zr-31Ti-18Nb alloy during cold rolling contributed to the improvement of {001}<110> deformation cube texture. This contributed to the preferential orientation of the directions <001> and <110> parallel to ND and RD (TD) directions, accordingly. The minimum values of the Young's modulus were typical for areas where low-module <001> orientation prevailed, and the maximum values of the Young's modulus were characteristic for areas with high-modules <110> orientations. So, in the alloy deformed by 84 %, the lowest values of the Young's modulus were obtain in the rolling plane up to 53 GPa, and the highest values in plane perpendicular to the rolling direction up to 70 GPa.
