Homogenization is one of the critical stages in the post-heat treatment of additive manufacturing (AM) component to achieve uniform microstructure. During homogenization …
The mechanisms of dislocation/precipitate interactions were analyzed in an Al–Cu alloy containing a homogeneous dispersion of θ′ precipitates by means of discrete dislocation …
A crystal plasticity computational homogenization framework is proposed to simulate the cyclic deformation of polycrystalline alloys that exhibit Bauschinger effect, mean stress …
The mechanisms of dislocation/precipitate interaction as well as the critical resolved shear stress were determined as a function of temperature in an Mg–4 wt% Zn alloy by means of …
The influence of different types of precipitates (either Guinier-Preston zones, θ ″or θ′) on the critical resolved shear stress and strain hardening was determined by means of …
