Mechanical Properties, Including Fracture Toughness Fatigue, Corrosion Characteristics and Fatigue-Crack Propagation Rates of Stress-Relieved Aluminum Alloy Hand Forgings

Abstract

A total of 38 of 40 hand forgings ordered for the investigation have been received to date. The alloys and tempers include 2014-T652, 2024-T852, 7075-T7352 and 7079-T652, in thicknesses ranging from 2 to 6 inches. Preparation of specimens for the tensile, compressive, shear, bearing, fracture toughness, axial-fatigue, corrosion and fatigue-crack propagation tests have been initiated. Tensile properties in the longitudinal, long-transverse and short- transverse directions have been determined for five of the hand forgings.
