METALLURGICAL CHARACTERISTICS OF HIGH STRENGTH STRUCTURAL MATERIALS

Abstract

A progress report covering research studies in high strength hull structural materials, conducted in the period September 1964 to December 1964, is presented. Included in the report are fracture toughness studies on: (1) titanium alloys as related to processing variables (including diffusion-bonding) , thickness, and heat-treatment, (2) aluminum, (3) high strength steels relating primarily to the 5Ni-Cr-Mo-V steels, and (4) a nickelberyllium alloy. Low cycle fatigue crack propagation studies on several titanium alloys are presented as well as a general review of the status of the titanium casting industry. The U. S. Naval Research Laboratory's new 240,000 ft-lb laboratory drop-weight bulge testing facility is described and a preliminary correlation of the results obtained with it and the explosion bulge test are presented. The results of a study using fatigue cracked and side notched Charpy specimens in impact and slow bend testing on a wide variety of steels is given.
