Mechanism of microstructure and mechanical properties improvement through ultrasonic rolling pressing layer-by-layer and adaptive ultrasonic rolling method research in AlSi10Mg laser powder bed fused

Journal of Materials Research and Technology
In the process of laser powder bed fusion (L-PBF), the high-speed movement of the laser heat source causes uneven temperature and stress fields, thus, it results in dendrites, pores, micro cracks and residual stresses.

Experimental methods in chemical engineering: Cyclic voltammetry—CV

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Cyclic voltammetry (CV) is a foundational electroanalytical technique for investigating redox behaviour and evaluating material performance across fields such as molecular electrochemistry, electrocatalysis, sensing, and energy storage. Despite its widespread use, a gap remains between formal electrochemical theory and the practical data ...

Effect of Layer Thickness and Scanning Parameters on Melt Pool Geometry and Track Continuity in Powder-Bed Arc Additive Manufacturing

Metals
Powder-bed arc additive manufacturing (PBAAM) may reduce the cost of powder-bed metal additive manufacturing and enable thicker layers than laser powder bed fusion (LPBF), but melt-track stability limits are not well established.
