INVESTIGATION OF FRACTURE TOUGHNESS IN HIGH STRENGTH ALLOYS.

Abstract

A comprehensive investigation of the fracture toughness of 4335-V steel tempered in the range of 400 to 800 F was carried out based primarily on precracked Charpy impact and slow bend tests of regular and brittle-boundary specimens with thicknesses in the range of about 0.04 to 0.40 inch. These tests were supplemented by notched and unnotched tensile tests, and by metallographic and fractographic examinations using both light and electron microscopy. (Author)
