Adiabatic Shearing in Ferrous Alloys.
Abstract
The dynamic deformation studies were carried out using a modified compressed air gun at Drexel University. The flat-nosed projectiles were made of hardened tool steel approximately 0.6 inches in diameter and weighing about 0.25 lb. For the most part the projectiles were 'stepped'. In other words, the actual penetration attempt of the plate targets was made by a short cylindrical flat-nosed step at the front of the projectile. This step gave the relatively heavy projectile a better chance of penetrating the target at the relatively low velocities that could be generated by the air gun. It also limited the penetration to the height of the step or less. The targets were 1/4 inch to 5/16 inch plates, cut either from plate material of that thickness or removed from 1 inch rounds, depending on availability. Preliminary tests showed that for the materials studied there is no significant orientation effect relative to the direction of working of the target material. (Author)
