Over the past decade, a concentrated effort has been made by both producers and aerospace users of titanium alloys to develop alloys for future aircraft applications. This effort has been motivated to a large extent by the advent of new design criteria and concepts such as fracture mechanics and design-to-cost. ti-6AI-4V, the workhouse of titanium alloys in aircraft structures, is beeing pushed to its technological limits to satisfy these criteria and, in some instances, is falling short of meeting imposed requirements. A new titanium alloy CORONA-5A, has been developed specifically to meet the needs of aircraft applications designed to fracture mechanics criteria. This report presents results of a programm aimed at demonstrating the feasibility of producing CORONA-5 on a production scale, evaluating its strength versus toughness characteristics over a wide range of producible strength levels, and making it available to investigators other than the developing agencies for their independent evaluation of its properties. In addition, results are presented herein of detailed material characterizations of selected forgings produced under a previous development contract.
