Effect of Preliminary Tension and Conditions of Artificial Aging on the Microstructure and Properties of Al – Li Alloy 2A97-T3

  • Published:
Metal Science and Heat Treatment Aims and scope

The effect of various aging modes and preliminary tension (3%) on the microstructure and mechanical properties of Al – Li alloy 2A97-T3 (1.31% Li, 3.55% Cu, 0.37% Mg, the remainder aluminum) is studied. Scanning electron microscopy in combination with energy-dispersive spectroscopy and EBSD analysis are applied. The ultimate tensile strength is determined.
