Mechanical Properties of 7076-T6 Aluminum Alloy

Abstract

This report documents a collaborative material characterization study of 7076-T6 forged aluminum performed by the NAVAIRSYSCOM Materials Division and Hamilton Sundstrand, sponsored and coordinated by the NAVAIRSYSCOM Engineering Specialties Divsion. The purpose was to determine the mechanical properties of the alloy to support the development of a fatigue allowables curve used for life assessment of 54H60 propeller blades. Specimens were fabricated from unused propeller forgings and tested at room temperature in ambient laboratory conditions using servo-hydraulic mechanical testing equipment. Tensile properties, fatigue crack growth rates, and stress life behavior were charactenzed using standard ASTM test procedures. A fatigue strength value was determined using a method developed by Hamilton Sundstrand. The period of testing spanned January through November 1999.
