Abstract : Two compositions of intercritically rolled homogeneous steel armor were evaluated by quasi-static and dynamic tests. Cross-rolling just below the intercritical temperature resulted in improved fracture toughness at the high-hardness levels (55 and 58 HRC). Taylor cylinder ballistic impact tests indicated a dynamic stress more than double the quasi-static yield stress. The use of this test for evaluating potential high-hardness armor material is discussed. (Author)
