Using Atom Probe Tomography (APT) and Phase Field Crystal ( PFC ) modelling, the early-stage precipitation phenomenon is investigated for naturally- and artificially-aged Al–Mg–Si alloys of two different Mg/Si ratios, i.e. 1 and 2. It is shown th

Strengthening in age-hardenable alloys is mainly achieved through nano-scale precipitates whose formation paths from the atomic-scale, solute-enriched entities are rarely analyzed and understood in a directly verifiable way. Here, we discover a pathw

A model is proposed for the variation of the yield strength of nickel-based superalloys as a function of chemical composition. Consistent with hardening theory, alloy strength is assumed to be proportional to the product of the anti-phase boundary (A

Al-Mg-Si-(Cu), i.e. AA6xxx, alloys are widely used light alloys which can be effectively strengthened through precipitation hardening. The final microstructure, and thus properties, of these alloys after common artificial aging treatments are largely

The chemistry of the Ni-base superalloys used for turbine disks is critiqued by making use of the recently developed Alloys-By-Design computer-based tools. Compositions within the Ni-Cr-Co-Al-Ti-Mo-W-Ta(-Zr-C-B) design space are evaluated virtually.

Discrepancies between the strength of slip systems determined directly from Mg single-crystal studies and those estimated from polycrystal simulations of Mg alloys are known to exist. These discrepancies have prohibited the direct use of single-cryst

Various self-consistent polycrystal plasticity models for hexagonal close packed (HCP) polycrystals are evaluated by studying the deformation behavior of magnesium alloy AZ31B sheet under different uniaxial strain paths. In all employed polycrystal p

The tensile and compressive yielding of cast Mg–Zn alloys, with varying grain sizes and compositions ranging from 0 to 2.3 at.% Zn, are simulated using a polycrystal plasticity model. The results are used to determine the grain size and composition

Experimental confirmation of various grain scattering theories exist but there are still outstanding questions concerning the characterization of microstructure using ultrasound. In this study, high purity niobium serves as a model material devoid of
