Abstract

The role played by small additions of chromium and zirconium on the “quench-sensitivity” of Al-Zn-Mg-Cu high purity alloys has been studied. The effects of the quench rate reduction have been evaluated by mechanical testing; the associated microstructural features have been investigated by electron microscopy. The obtained data adequately explain the mechanisms of the “quench-sensitivity”.
