Rapid solidification in laser additive manufacturing facilitates the precipitation of metastable phases in aluminum alloys. These metastable phases significantly enhance the strength by forming a high‐volume fraction of precipitates with an order of magnitude reduced sizes and smaller interspacing, effectively impeding dislocation motion. Consequestly,

This study develops a lightweight AlFeNiTiV complex concentrated alloy (density: 6.83 g cm−3) through Cu microalloying and lattice coherency tuning. The alloy exhibits ultrahigh compressive strength exceeding 3.3 GPa, 11.8% strain, and retains a yield strength of 1311.6 MPa at 600 °C, demonstrating a phase interface strategy for high‐temperature ...

Duplex aluminized coatings [PDF]
The surface of a metallic base system is initially coated with a metallic alloy layer that is ductile and oxidation resistant. An aluminide coating is then applied to the metallic alloy layer.

Advanced tungsten fiber-reinforced nickel superalloy [PDF]
Matrix composition, fabrication technique, and fiber diameter were selected to minimize fiber-matrix reaction and preserve composite strength. Composites may be used in place of superalloys where higher strength or greater strength-to-density ratios are ...
