Abstract Scope Success of many forming operations depends fundamentally on the strain-hardening capability of the deforming materials. As many structural alloys are comprised of precipitation-hardening systems, the phenomenon of dynamic precipitation, which may occur during forming, is an important factor in governing the ductility of the alloys. The reason is the unusual strain-hardening behavior imparted by dynamic precipitation. In this study, Al-Zn-Mg-Cu system that is widely used in structural applications is investigated for coupled effects between deformation and precipitation of GP-zone/MgZn2 phases by in-situ tension testing simultaneous with synchrotron X-ray scattering, and by transmission electron microscopy experiments. Mathematical modeling of shearable to non-shearable transition in precipitation hardening phenomena is conducted for an in-depth analysis of deformation-precipitation couplings and its correlations with strain-hardening behavior. Methods to overcome the strength-ductility paradox in precipitation-hardening alloys will be discussed.
