AFML-TR-77-102, TECHNICAL REPORT: EXPLORATORY DEVELOPMENT FOR DESIGN DATA ON STRUCTURAL ALUMINUM ALLOYS IN REPRESENTATIVE AIRCRAFT ENVIRONMENTS (JUL-1977)

AFML-TR-77-102, TECHNICAL REPORT: EXPLORATORY DEVELOPMENT FOR DESIGN DATA ON STRUCTURAL ALUMINUM ALLOYS IN REPRESENTATIVE AIRCRAFT ENVIRONMENTS (JUL-1977)., The mechanical properties, fracture toughness, fatigue, fatigue-crack growth rates in three environments and corrosion characteristics of 10 lots each of 20148-T851, 7050-T7351 and 7475-T7351 plate and 2219-T852 hand forgings have been evaluated. Data for establishing MIL-HDBK-5 values, including modulus of elasticity and stress-strain are presented.
