Full-text available
Twin, dislocation, and grain boundary interaction in hexagonal materials, such as Mg, Ti, and Zr, has critical influence on the materials’ mechanical properties. The development of a microstructure-sensitive constitutive model for these deformation mechanisms is the key to the design of high-strength and ductile alloys. In this work, we have develo...

There are several facets of aluminum when it comes to sustainability. While it helps to save fuel due to its low density, producing it from ores is very energy-intensive. Recycling it shifts the balance towards higher sustainability, because the energy needed to melt aluminum from scrap is only about 5% of that consumed in ore reduction. The amount...

The complex interplay between chemistry, microstructure, and behavior of many engineering materials has been investigated predominantly by experimental methods. Parallel to the increase in computer power, advances in computational modeling methods have resulted in a level of sophistication which is comparable to that of experiments. At the continuu...

The electrochemical properties of high strength 7xxx aluminium alloys strongly depend on the substitutional occupancy of Zn by Cu and Al in the strengthening η-phase with the two-sublattice structure, and its microstructural and compositional prediction is the key to design of new generation corrosion resistant alloys. In this work, we have develop...

The grain boundary (GB) microchemistry and precipitation behaviour in high-strength Al-Zn-Mg-Cu alloys has an important influence on their mechanical and electrochemical properties. Simulation of the GB segregation, precipitation, and solute distribution in these alloys requires an accurate description of the thermodynamics and kinetics of this mul...

An ultrahigh strength Mg-10Gd-4Y-1.5Zn-0.5Zr alloy was prepared by the combined process of extrusion, pack-forging and aging treatment. The resultant alloy possesses a bimodal grain structure, a high number density of nanoprecipitates and long period stacking ordered (LPSO)/stacking faults (SFs). Numerous dispersive precipitates formed after the ag...

open access: https://www.sciencedirect.com/science/article/pii/S0045782520302139 A chemo-mechanical model for a finite-strain elasto-viscoplastic material containing multiple chemical components is formulated and an efficient numerical implementation is developed to solve the resulting transport relations. The numerical solution relies on inverti...

Full-text available
Predicting process–structure and structure–property relationships are the key tasks in materials science and engineering. Central to both research directions is the internal material structure. In the case of metallic materials used for structural applications, this internal structure, the microstructure, is the collective ensemble of all equilibri...
Article

Although magnesium alloys deform extensively through shear strains and crystallographic reorientations associated with the growth of twins, little is known about the strengthening mechanisms associated with this deformation mode. A crystal plasticity based phase field model for twinning is employed in this work to study the strengthening mechanisms...

A chemo-mechanical model for a finite-strain elasto-viscoplastic material containing multiple chemical components is formulated and an efficient numerical implementation is developed to solve the resulting transport relations. The numerical solution relies on inverting the model relations in terms of the chemical potential. In this work, a semi-ana...

Magnesium (Mg) alloys with hexagonal close-packed (HCP) structure usually have a poor ductility at room temperature. The addition of yttrium (Y) can improve the ductility of Mg alloys. To understand the underlying mechanism, crystal plasticity finite element method (CPFEM) was employed to simulate the tensile deformation of a Mg−0.8 wt% Y alloy. Th...
