PLANE STRAIN FRACTURE TOUGHNESS DATA FOR HANDBOOK PRESENTATION

Abstract

An experimental program was conducted to determine the plane strain fracture toughness (K sub IC) of the following classes of: (1) AISI Alloy Steels (4340, 4140); (2) 5Cr-Mo-V Steels; (3) Precipitation-Hardening Stainless Steels (17-7 PH, PH 15-7 Mo, 17-4, AM355); (4) Titanium Alloy, Ti-6Al-4V. The precracked notched bend test was used as the test method and several heats of each material were evaluated over a range of test temperatures from -100 to +200 deg F. The (K sub IC) values, obtained under conditions which were believed to provide valid plane strain fracture toughness numbers, were compiled for possible presentation in handbook form. The method of presentation involved plotting (K sub IC) both as a function of material strength and test temperature. The resulting curves provide representative (K sub IC) figures which can aid in the selection of materials for reliable performance.
