Abstract : Cast steels, with superior ductility, can be produced by unidirectional solidification, which results in minimum macrosegregation and macroporosity and less microporosity than is found in conventional castings. To produce a superior wrought steel armor, techniques were established for casting unidirectionally solidified slabs 10 by 16 by 5-1/2 inches weighing about 240 pounds. The slabs were homogenized by holding in evacuated stainless-steel boxes for 64 hours at 2400 F, and rolled to plates for ballistic testing. (Author)
