NEW ALUMINUM AIRCRAFT ALLOYS FOR THE 1980'S

NUOVO LEGHE AERONAUTICHE DI ALLUMINIO PER IL 1980

The paper was presented at the Torino International Meeting on Aluminum Alloys in the Aircraft Industries (October 1-2, develop an improved 2000-series alloy possessing an 8% increase in tension ultimate strength compared to 2024-T351, and a 7000-series alloy with an 11% increase in compression yield strength compared to 7075-T651. The alloy development studies which led to the current program are summarized. These studies examined the effects of Zn/Mg ratio, copper content, purity level (0.01.25% Fe and Si), ratio, copper content, purity level (0.01-0.25% Fe and Si), grain refiners (Zr, Cr, and Mn), thermomechanical processing, and heat treatment on strength, fracture, toughness, and fatigue crack growth rates.
