ABSTRACT:
According to typical inventive practice, a first metallic material is poured into a mold including a bottom inside surface having regularly arrayed rises (truncated spherical convexities). The molten first metallic material cools and solidifies to include a surface correspondingly having regularly arrayed dents (truncated spherical concavities). The resultant “inner casting” is removed from and repositioned in the mold so that the inner casting's dent-laden surface faces upward. Ceramic spheres are placed in the dents. A second metallic material (having a higher melting point than the first metallic material) is poured into the mold with the inner casting and spheres in place. The molten second metallic material cools and solidifies as an “outer casting” surrounding the inner casting and the spheres. The resultant integral armor structure includes the inner casting, the outer casting, and the spheres, each sphere embedded partially in the inner casting and partially in the outer casting.
