| Abstract Scope |
ATI Titan 27® is a lightweight α/β titanium alloy capable of a 15% increase in strength/weight ratio compared to the industry workhorse Ti 6Al-4V. Though this Ti-Al-Sn-V-Co alloy is similar in microstructure to legacy α/β titanium alloys, it has a higher propensity for activating non-close packed c+a slip systems. This novel behavior enables high ductility in the alloy without sacrificing static properties and dynamic properties such as toughness and fatigue. The alloy’s wide hot working range enables tunable properties through thermomechanical processing and heat treatment. Titan 27® has been successfully produced in multiple product forms such as plate, sheet, bar, powder, and billet at production scale, and is an ideal replacement for Ti 6Al-4V in a variety of ballistic, structural, and dwell-sensitive applications. |
