TENSILE DEFORMATION CHARACTERISTICS OF TI-6AL-4V (ELI GRADE) AND EFFECT OF INTERSTITIAL CONTENT

Anisotropy in tensile deformation of the Ti-6Al-4V (Ti-31) and Ti-6Al-4V extra low interstitials (ELI grade) was investigated and effect of interstitial on tensile deformation was discussed. Also reported in brief the details of chemical composition, microstructure of Ti-6Al-4V (ELI grade).The study reveals the tensile strength is more in circumferential direction than radial direction for Ti-6Al-4V (ELI grade) and due low extra interstitials the strength of alloy decreases.
