Effect of Titanium Additions on the Aging Characteristics of an Al-Zn-Mg Alloy.
Abstract
A minute titanium addition (.04%) was added to an Al-Zn-Mg alloy in order to determine the effect of titanium on microstructure and aging characteristics of this alloy. Titanium was found to retard the kinetics of precipitation and to prevent solute segregation to grain boundaries on air quenching. Below G.P. solvus temperature, hardening of the alloy was due both to dislocation loop formation and to G.P. zone formation. Above G.P. solvus temperature, hardening was due only to formation of precipitate. These results have been explained in terms of titanium reducing the likelihood of the formation of solutevacancy complexes; causing a reduction in zinc and magnesium mobility. (Author)
