Mechanical Property Characterization of Thick Wall Ti-6Al-6V-2Sn Forging
Abstract
This paper addresses a mechanical property investigation on Ti-6Al- 6V-2Sn which is used for the rear body component of the T5119 artillery torsional impact test projectile. Quantities of this projectile were produced during 1988 and 1989 at the U.S. Army Materials Technology Laboratory (MTL) upon request from PM-NUC. These projectiles had been produced at MTL approximately 10 years ago. In the earlier work, a die which resulted in a forged wall thickness less than 1 inch, which is customary for this component, was used. In the recent program, a substitute die which resulted in a heavier forged wall thickness of approximately 1-5/8 inch had to be used. This was necessary due to the fracture failure of the customary die. Because of the time constraints placed upon MTL by PM-NUC to produce and deliver both the T5119 and T5106 test projectiles, time was not available to make a replacement die; therefore, it was necessary to conduct a heat treatment study of the thicker wall forgings in order to meet the mechanical property requirements for the rear body component.
