Influence of Scan Strategies in Electron Beam Powder Bed Fusion on Solidification, Microstructure, and High‐Temperature Compressive Properties of γ′‐Strengthened Inconel 738LC

Advanced Engineering Materials, EarlyView.
Experiments and thermophysical simulations were conducted to investigate the electron beam powder bed fusion electron beam (PBF‐EB/M) process for the γ′‐strengthened nickel‐based superalloy Inconel 738LC. The results demonstrate the impact of process‐induced microstructural variations on high‐temperature mechanical behavior, providing a basis for ...

The Influence of Field‐Assisted Sintering Technology (FAST) Temperature and Cooling Rate on the Microstructural Evolution in Gamma‐Titanium Aluminide Alloy GE4822

Advanced Engineering Materials, EarlyView.
Controlling the Field Assisted Sintering Technology (FAST) parameters, dwell temperature and cooling rate, significantly influences the microstructural evolution in titanium aluminide GE4822. Significant γ‐lamellar colonies develop only upon cooling through the α‐transus.

A possible theory for the interaction between convective activities and vortical flows [PDF]

Nonlinear Processes in Geophysics, 2011
Theoretical studies usually attribute convections to the developments of instabilities such as the static or symmetric instabilities of the basic flows. However, the following three facts make the validities of these basic theories unconvincing.

Investigating the effects of employing a cooling radiator on MHD natural convection by injecting MWCNTs into water

Ain Shams Engineering Journal, 2023
One of the best methods in thermal engineering for cooling a liquid is to use a radiator. Using the radiator mechanism in free convection systems is a successful and first idea to improve performance of natural convection systems, which have various ...

Synergistic Solar Interfacial Evaporation and Photocatalysis Enabled by a Hierarchical Porous Hydrogel Reactor

Advanced Functional Materials, EarlyView.
A tree‐inspired hydrogel interfacial reactor couples solar evaporation with photocatalysis for simultaneous desalination and waste water treatment. The bilayer design achieves 2.14 kg·m−2·h−1 evaporation rate with 79% dye degradation under one sun, demonstrating that photothermal heating and evaporation induced pollutant enrichment create a self ...

Advancements in Hypersaline Wastewater Treatment: The Promise of Quasi‐Liquid Surfaces to Reduce Salt Scaling

Advanced Functional Materials, EarlyView.
Durable quasi‐liquid polymer brush surfaces provide an anti‐scaling strategy for hypersaline brine evaporation and zero‐liquid‐discharge desalination. The smooth, liquid‐like QLS interface suppresses substrate‐side salt nucleation, promotes compact crystallization and dewetting, reduces crystal–surface contact area, and enables low‐adhesion salt ...
