Precipitation strengthening in an ultralight magnesium alloy [PDF]

Nature Communications, 2019
Solution treatment and quenching can strengthen magnesium-lithium-aluminium alloys, but this strength decreases with ageing. Here, the authors show this is due to semi-coherent nanoparticle precipitation followed by coarsening, and control the lattice ...

Precipitation Strengthening of Cu-Ni-Si Alloy. [PDF]

Materials (Basel), 2020
The work examines the effect of rhenium addition on the structure and properties of Cu–2Ni–1Si alloys. The aim of this work was to answer the question of how the addition of rhenium will affect the strengthening mechanisms of rhenium-modified, saturated, plastically deformed and aged Cu–2Ni–1Si alloys.

Microbial-Induced Carbonate Precipitation for Strengthening Soft Clay [PDF]

Advances in Materials Science and Engineering, 2020
Currently, calcite produced in sediments by microbial-induced carbonate precipitation (MICP) is mainly used as a strengthening binder in sand because sands are porous and have good permeability.

Effects of NiAl on precipitation behavior and mechanical properties of M2C strengthened secondary hardening steel

Journal of Materials Research and Technology
A novel dual-precipitation steel was developed by introducing NiAl into secondary hardening ultrahigh strength steel. This steel exhibited a yield strength of 1.9 GPa, an ultimate tensile strength of 2.3 GPa, and an elongation of 9%.

Precipitation-strengthening effects in iron-aluminides

, 1995
The purpose of this work is to produce precipitation to improve both high-temperature strength and room-temperature ductibility in FeAl-type(B2 phase) iron-aluminides. Previous work has focused on primarily wrought products, but stable precipitates can also refine the grain size and affect the properties of as-cast and/or welded material as well.
