The Influence of Processing on the Microstructure and Properties of the Titanium Alloy Ti-5111

Abstract

The physical, mechanical, and corrosion properties of titanium and its alloys are attractive for applications in the U.S. Navy in view of design requirements for increased reliability with reduced maintenance and weight. The Naval Surface Warfare Center, in cooperation with Titanium Metals Corporation, developed the Ti-5Al-1Sn-1Zr-1V-0.8Mo (Ti-5111) alloy as a lower cost alternative to previous high-strength titanium alloys exclusive to Navy applications. The influence of heat treatment on the microstructure and mechanical properties was examined in the Ti-5111 alloy in both wrought and cast products. The effects of time and temperature on the microstructural evolution in this near-alpha alloy are assessed, and the relationships between microstructure and the corresponding tensile properties as well as impact and fracture toughness behavior are examined.
