Abstract
Substantial progress has continued in the US since the last (13th) World Titanium Conference with regards to titanium technology, products, processing, computational modeling tools and applications. Titanium components produced by additive manufacturing have been qualified and achieved production applications in commercial and military aircraft hardware. New high-performance titanium alloys have been developed for higher temperature service and applications requiring more demanding static and dynamic properties. Current production processes for titanium have been optimized, and new processes have been developed to further reduce cost and improve product quality. Titanium suppliers, OEM’s, government labs and academia are working closely together to address fundamental industry-wide issues. Computer modeling is now used extensively in industrial and research facilities to accelerate the pace and success of these developments.

A recent aerospace forecast by the Federal Aviation Administration (FAA) for fiscal years 2019 to 2039 expects air traffic to grow from 51.8 million in 2018 to 62 million in 2039
Good compatibility between titanium and carbon fiber composites has led to increased use of titanium in new airframe structures containing larger amounts of composites [2]
Performance, quality and cost requirements of titanium components drive the utilization of multi-disciplinary optimization methods that are well supported by Integrated computational materials modeling (ICME)
Summary
A recent aerospace forecast by the Federal Aviation Administration (FAA) for fiscal years 2019 to 2039 expects air traffic (i.e., number of landings and take offs) to grow from 51.8 million in 2018 to 62 million in 2039. These include developing new manufacturing processes to lower cost, improving performance of legacy and new titanium alloys to meet enhanced requirements for new applications, and developing computational materials models to reduce new alloy development cycle times and/or acceleration of process qualifications. New alloys have been developed to meet enhanced component requirements, and new technologies, such as Additive Manufacturing (AM) have seen insertion opportunities in aerospace applications.
