Abstract: A ballistic V50 evaluation of an experimental titanium alloy Ti108 was conducted to determine if lower alloys in a plate's content can provide slightly lower strengths with higher elongation and resistance to cracking while still meeting the minimum performance specifications outlined in MIL-DTL-46077G. A 3.1-inch-thick plate was provided by the Titanium Metals Corporation (Dallas, Texas) for the V50 evaluation. The projectiles used for the evaluation were the 20-mm M602 armor piercing with tracer (AP-T) and a 30-mm armor piercing discarding sabot (APDS). It was found that the Ti108 plate did not meet the minimum ballistic requirements for the 20-mm M602 AP-T threat, but did meet the requirement for the 30-mm APDS threat by 1 m/s. Future studies or adjustments to the chemistry of the Ti108 can be conducted to optimize ballistic performance.
