EVALUATION OF DUAL-HARDNESS TITANIUM ALLOY ARMOR

Abstract

A program to evaluate the producibility and ballistic characteristics of dual-hardness titanium utilizing a new class of high-hardness titanium alloys has been conducted. The results of studies to optimize the composition and heat- treatment schedules for the hard alloys are presented. The approach to melting and fabrication of 25-lb ingots of these alloys is discussed. Factors influencing the selection of a suitable back-face alloy are reviewed, and methods for preparing dual-hardness composite test plates from the optimum materials are detailed. Results of ballistic tests with 0.30- and 0.50-cal AP/M2 projectiles are presented and correlated with the metallurigcal structure and properties of the composites. An assessment of the technical feasibility of producing an effective dual-hardness titanium armor based on this concept is made, and recommendations for continuing work are presented.
