Preparation and Characterization of Ti‐6‐4 and Ti‐8‐1‐1 Metal Matrix Composites with High Specific Stiffness Using Powder Hot Extrusion and Arc Remelting

Advanced Engineering Materials, Volume 26, Issue 14, July 2024.
Powder hot extrusion and heat treatment of titanium metal matrix composite's lead to high specific stiffnesses of 34.6 GPa cm3 g−1. Remelting, to simulate an additive manufacturing method, of these materials results in severe changes of the microstructure and a decrease in the mechanical properties even with ex situ reinforcements. Titanium alloys with

Ink‐Extrusion 3D Printing and Silicide Coating of HfNbTaTiZr Refractory High‐Entropy Alloy for Extreme Temperature Applications

Advanced Science, Volume 11, Issue 17, May 8, 2024.
This work demonstrates that an oxygen‐sensitive refractory high‐entropy alloy (RHEA) can achieve architecture freedom and good oxidation resistance by a series of simple processing steps: i) 3D ink‐extrusion printing, ii) interdiffusion‐sintering, and iii) silicide coating.

Tooling in Spark Plasma Sintering Technology: Design, Optimization, and Application

Advanced Engineering Materials, Volume 26, Issue 5, March 2024.
The review highlights all aspects of tooling in spark plasma sintering (SPS) technology starting from basic configuration to design adapted to the manufacturing of complex‐shaped parts. Modeling and optimization are essential issues in SPS tooling design. Upscaling and industrialization of SPS require multiple die tooling.

Influence of surface treatment on metal dusting resistance of welds

Materials and Corrosion, Volume 75, Issue 3, Page 371-385, March 2024.
Fe contaminations enhanced metal dusting pit formation on brushed welds of Ni‐based alloys. The best performance of the welds was achieved by grinding, this is attributed to the deformation of the sub‐surface zone. Additional protection by on‐site slurry aluminization was successfully demonstrated.

Interdiffusion Behavior in Aluminide Coatings for Power Generation Applications [PDF]

, 2003
One of the critical issues for the application of iron aluminide coatings is the loss of Al from the coating into the Fe-base substrate alloys which do not contain aluminum.
