Abstract : Explorations into the ocean and space demand structural materials of higher fracture toughness and strength-to-weight ratio. Nickel-steels and titanium alloys appear promising for such applications. This report presents fracture toughness data obtained through nearly 600 tests performed on specimens from 134 plates of materials in these two classes. (Author)
