【 摘 要 】

The crystallographic texture of Ti-29Nb-9Ta-10Zr alloy is studied after cold-rolling with different amounts of thickness reduction, up to 60%. The major texture components developed during cold-rolling were: gamma-fibre components: {111}< 1 (1) over bar0 >, {111}< 0 (1) over bar1 >, {111}< 1 (2) over bar1 > and {111}<(1) over bar(1) over bar2 >; texture component: {112}<(1) over bar(1) over bar1 > and texture components: {001}< 0 (1) over bar0 > and {010}< 001 >. Besides crystallographic texture the resulted mechanical properties were studied by nanoindentation. It was showed that the decrease in Young's modulus after different cold-rolling stages is mainly attributed to the stress-induced alpha-Ti phase formation. At 60% cold-rolling thickness reduction obtained an elastic modulus close to 45.29 +/- 3.81 GPa, coupled with an average Vickers microhardness close to 279.83 +/- 4.28 HV. (C) 2013 Elsevier B.V.
