Carbon partitioning during quenching and partitioning heat treatment accompanied by carbide precipitation

Acta Materialia, 2015
Abstract Carbon partitioning from martensite into austenite in the quenching and partitioning (Q&P) process has been suggested to be controlled by the constrained carbon equilibrium (CCE) criterion. It defines an approach for predicting the carbon concentration in austenite under the condition that competing reactions such as carbide formation and ...

On the role of the solute partitioning and chemistry in initial precipitation of Ω plates

Materials Science & Engineering A: Structural Materials: Properties, Microstructure and Processing, 2019
Abstract The control of the precipitation of Ω phase is the critical factor that determines the mechanical properties and performance of Al-Cu-Mg-Ag alloys at elevated temperatures. As the most important components for Ω nucleation, the Mg and Ag additions usually plays a key role in affecting the precipitation kinetics of Ω phase.

Controlling the nucleation of multiple precipitates in precipitation-strengthened steel through Mo partitioning

Materials Science and Technology, 2022
In this study, atom probe tomography and first-principles calculations were used to investigate the influence of Mo addition on multiple precipitates, including isolated NiAl-based precipitates as well as NiAl-based and Cu-rich co-precipitates, in high-strength ferritic steel. The co-NiAl-based precipitates were experimentally confirmed to be nucleated

Valuing Urban Tree Impacts on Precipitation Partitioning

2020
Trees impact surface stormwater runoff, soil moisture, streamflow, water quality, and air temperatures by intercepting precipitation (rain and snow), enhancing soil water infiltration, shading surfaces, and evapotranspiring water. These impacts affect human health and well-being.

Elemental partitioning as a route to design precipitation-hardened high entropy alloys

Journal of Materials Science & Technology, 2020
Precipitation-hardened high entropy alloys (HEAs) with carefully tuned compositions have shown excellent mechanical properties, demonstrating great potential for engineering applications. However, due to the lack of precise multiple phase diagrams, the composition design of multi-principal-component HEAs still inevitably relies on the extremely time ...
