Evaluation of Prototype Secondary Hardening Steels for Armor

摘要

Three ARL .SRG secondary hardening armor steels designed using the THERMOCALCthermomechanical database and software system were subjected to ballistic impact using U.S. .30 caliber AP M2 and U.S. .50 caliber AP M2 projectiles. Against the .30 caliber projectile, each of the three steel alloys showed ballistic tolerance comparable to AerMet 100 Steel. Against the .50 caliber projectile, the ballistic test plates did not perform as well as AerMet 100. The results of this test series will be the basis for design and evaluation of more prototype armor steels based on secondary hardening.
