Effect of La addition on Ag-rich phase formation and mechanical properties of Cu-2Ag alloys

Journal of Materials Research and Technology, 2022
A series of novel Cu-2Ag-xLa alloys with reinforced mechanical properties and enhanced electrical conductivities are developed. The effects of La addition on the microstructural features and mechanical properties of as-cast and solution treated Cu-2Ag ...

A multidisciplinary approach to study precipitation kinetics and hardening in an Al-4Cu (wt. %) alloy

, 2018
A multidisciplinary approach is presented to analyse the precipitation process in a model Al-Cu alloy. Although this topic has been extensively studied in the past, most of the investigations are focussed either on transmission electron microscopy or on ...

Influence of severe plastic deformation on the precipitation hardening of a FeSiTi steel [PDF]

, 2012
The combined strengthening effects of grain refinement and high precipitated volume fraction (~6at.%) on the mechanical properties of FeSiTi alloy subjected to SPD processing prior to aging treatment were investigated by atom probe tomography and ...

Effect of shear-coupled grain boundary motion on coherent precipitation

, 2019
We examine the interaction between precipitates and grain boundaries, which undergo shear-coupled motion. The elastic problem, emerging from grain boundary perturbations and an elastic mismatch strain induced by the precipitates, is analysed.

Microstructure Dependence of Magnetic Properties for Al_1.5Fe₃Co₃Cr₁ Multi-Principal-Element Alloy

Metals
This study focuses on the microstructures and soft-magnetic properties of the Al1.5Fe3Co3Cr1 multi-principal-element alloy (MPEA) in different states. The MPEA was prepared using arc melting and suction-casting, followed by various heat treatments.

Mapping stress heterogeneity in single-crystal superalloys by novel submicron-resolved X-ray diffraction

Materials Research Letters
Coherent precipitation, a common strengthening approach, is typically subjected to spatial non-uniformity due to microscopic segregation, leading to multi-scale stress heterogeneity.
