Understanding the Effect of Resistance Temperature Detector Temperature Controllers on Microstructural Alignment in Magnetic Freeze Casting

Advanced Engineering Materials, EarlyView.
The effect of temperature controllers that are commonly used in freeze‐casting is investigated in this work. Temperature controllers are observed to generate a voltage in the slurry. Microstructural alignment and ultimate compressive strength data show this voltage to interfere with the ability to align the microstructure using magnetic fields ...

Challenges during Flash Lamp Annealing of Aerosol‐Deposited Barium Titanate Films

Advanced Engineering Materials, EarlyView.
Aerosol deposition is used to rapidly deposit barium titanate films with thicknesses ranging from 2 to 16 μm at room temperature, eliminating the need for further densification. However, to recover the electromechanical properties, annealing is required, which limits the usage of temperature‐sensitive substrates.

Enhanced Oxidation and Thermal Shock Resistance of N‐type Mg2Si0.89(Sn0.1,Sb0.01) Thermoelectric Material via Cr0.9Si0.1 Coating

Advanced Engineering Materials, EarlyView.
Cr0.9Si0.1 protective coatings are developed to enhance the thermal‐shock and oxidation resistance of Mg2Si0.89(Sn0.1,Sb0.01) thermoelectric (TE) materials. The coating forms a dense and adherent barrier that suppresses oxygen diffusion and mitigates mechanical degradation during cyclic oxidation, demonstrating its potential to improve the long‐term ...
