Structure-property models in Al-Zn-Mg-Cu alloys: A critical experimental assessment of shape castings

The applicability of existing process models to predict the total yield strength of Al-Zn-Mg-(Cu) wrought alloys was investigated with the aid of our experimental results that were obtained for the cast components of these alloys. The cast specimens were prepared using a new process known as the Controlled Diffusion Solidification (CDS) technology. Three distinctive compositions from the realm of Al-7000 alloy family were selected with a sum …
