Titanium alloys have long been used for reducing system weight in airframe structure and jet engine components. The high cost of titanium however, has historically prevented the application to military ground vehicles. In recent years, the cost of titanium has fallen relative to the cost of composite and ceramic armors and titanium is now a valid option for some Army applications, whether for weight reduction or improved ballistic performance. The distinct advantages of low density, high strength, a large competitive industrial base, and well established fanning and shaping techniques establishes titanium as an excellent material for many military applications. The U.S. Army Research Laboratory (ARL) has invested significant research efforts in understanding the material processing requirements for ground versus aerospace applications and this paper will provide an overview of that research. A major concurrent effort has been amending existing military specifications to allow the use of lower cost, higher oxygen content titanium alloys that meet specific ground applications. The paper will end with a review of some of the past and current applications of titanium on US Army platforms and augments previous presentations given in this forum in 2007, 2008 and 2009.
