METALLURGICAL CHARACTERISTICS OF HIGH STRENGTH STRUCTURAL MATERIALS.
Abstract
A progress report covering research studies in high strength, hull structural materials, conducted in the period of November 1963 to January 1964 is presented. These studies included the development of preliminary flaw size-stress relationships for fracture of quenched and tempered and maraging steels and of titanium alloys. Additional information was developed on the relationships of various fracture tests for these materials. Heat-treatment studies for steels and titanium alloys provided an expanded frame of reference for establishing the optimum fracture toughness level to be expected for specific levels of yield strength. The relationship of fatigue crack propagation rate to total strain range was determined for various quenched and tempered steels. (Author)
