The purpose and scope of the present research were to produce a strong 112 111 texture in the quenched and tempered plates of the Ni-Cr-Mo and Mn-Mo-B conventional armor steels by appropriate thermomechanical processing and to study its effects on the mechanical and ballistic properties of the plates. Also, the effect of carbon content above 0.40 percent on the ballistic properties of textured 5Ni-steel armor was to be investigated. Results indicated that a strong 112 111 texture could be produced in plates of both armor steels. Because of the relatively low hardenabilities of these steels, particularly the Ni-Cr-Mo steel, ferrite formation could not be prevented in the on-line quenched plates. The ballistic test results were widely scattered.
