Abstract

This study focuses on the quench sensitivity of sheets made of V-1341 aluminum alloy of the Al–Mg–Si system. Using transmission electron microscopy, energy-dispersive X-ray spectroscopy), differential scanning calorimetry, and thermodynamic modeling, some features of precipitate formation during slow quenching (below the critical cooling rate) were examined. It has been determined that quench-induced precipitates form on the surface of α-phase dispersoids (Al15(Mn, Fe)3Si2) as coarse rod-like precipitates of β-type phases, with some inclusions potentially containing copper.
