Residual stress reduction in 7175-T73, 6061-T6 and 2017A-T4 aluminium alloys using quench factor analysis

Influence of Temperature-Dependent Properties of Aluminum Alloy on Evolution of Plastic Strain and Residual Stress during Quenching Process

“…For this purpose, fast cooling rates are required to avoid or limit precipitation during the quenching process [2]. However, high cooling rates result in serious inhomogeneous deformations and lead to high residual stresses [3], which deteriorates the mechanical properties and dimensional stability [4,5], and also have important impact on fatigue properties [6][7][8]. Therefore, it is important to study how to control the residual stresses.…”

Strengthening behavior of Al–Cu–Mg alloy sheet in hot forming–quenching integrated process with cold–hot dies

“…However, the temperature of forming dies should be carefully controlled and it is unpractical to elevate the dies temperature to a too high level. Otherwise, it cannot ensure enough cooling ability, resulting in the coarse precipitates precipitating at sensitive temperature range and the resultant weak strengthening [9]. The authors have investigated the strengthening of 6A02 aluminum alloy sheet in hot forming-integrated process with both hot dies [10].…”

A modeling of residual stress in stretched aluminum alloy plate

“…For instance, Dolan and Robinson (2004) issued a method to predict residual stress in quenched 7175-T73 plate by using time temperature property curves, which was developed by Fink and Willey (1948) and improved by Evancho and Staley (1974).…”
