Abstract Scope |
High-strength titanium alloys such as Ti-10V-2Fe-3Al (Ti-10-2-3) and Ti-5Al-5V-5Mo-3Cr (Ti-5553) are currently used in critical airframe applications such as landing gear, wing box structural members and engine nacelles. In a solution treated and aged condition, these alloys exhibit a high tensile strength (above 180 ksi) with moderate fracture toughness. Conversely, in the beta annealed condition, these alloys exhibit significantly higher fracture toughness with lower tensile strength. Experiments conducted at ATI have identified a combination of alloy composition and processing parameters resulting in a new titanium alloy with an improved tensile strength and toughness capability. This presentation will focus on the effects of hot working parameters on the strength, ductility and damage tolerance of a new metastable beta titanium alloy: ATI Titan 23™. |
