Induction Heat Treatment - Phase I - Technology to Produce Monolithic Gradient Hardness Steel Armor.

Abstract

This report details the results of Phase I of the Dual Hard Steel Armor Program funded by the PM, Survivability, U.S. Army Tank-Automotive Command (TACOM). This report investigates the use of an induction heat-treating process to produce a gradient hardness monolithic steel armor to complement MIL-A-46099, Armor Plate, Steel, Rolled-Bonded, Dual-Hardness, for thicknesses of approximately 0.5 in. Results of this investigation indicate that a conventionally heat-treated steel armor plate (tempered to a hardness range of Rc 42-52; induction-hardened to approximately Rc 60 and induction tempered to approximately Rc 50 with a high hardness thickness of approximately 40%) will provide acceptable ballistic results when compared to the ballistic requirements of MIL-A-46099. Future efforts (Phase II) will include optimization of the composition, hardness levels, and thickness gradients. Production-size plates will also be processed to ensure that the technology can be transitioned from the laboratory to production.
