Effect of Crystallographic Texture on the Mechanical and Ballistic Properties of Steel Armor.

摘要

Continuing the study of the effect of crystallographic texture on the mechanical and ballistic properties of steel armor, 1/2-inch-thick plates of a medium-carbon 5Ni-Si-Cu-Mo-V steel were produced with a (110) or an approximate (111) texture of various intensities. Although the intensities of these textures in the present plates (2.80 or 2.45 times random) were as strong as those in the small-size specimens previously processed under strictly controlled conditions, their effects on the ballistic performance were not sufficiently great to be of practical significance. For both these textures and at the relatively low intensity levels, the V50 ballistic limits appeared to increase with increasing texture intensity. Consistent with the relatively low texture intensities and ballistic limits, the spalling tendencies of the plates were mostly weak to moderate.
