The present research program consisted of two parts. 1 To produce a number of 6- by 12- by approx. 12-inch armor plates having strong 112 111 texture with various degrees of intensity by the thermomechanical processing treatments of essentially the same medium-carbon, 5Ni-Si-Cu-Mo-V steels used previously, and to establish the reproducibility of texture, microstructure, hardness, and ballistic performance of these steel armor plates. Results indicated that the reproducibility of the structure and properties of these steel armor plates was excellent. The ballistic limit increased with the texture intensity in nearly the same manner as observed previously. 2 To explore the possibility of producing a nearly 111 texture with various degrees of intensity in small size specimens cross-rolled at 1500 F to various reductions then quenched, and to establish a procedure for optimizing this texture in larger 6- by 12- by approx. 12-inch plates.
