Wire arc directed energy deposition (WDED) is a robust alternative for large-scale metal printing. It offers high deposition rates, excellent material and energy efficiency, and reduced waste material compared to conventional manufacturing processes. This article describes a study that employed a combination of standard and advanced characterization techniques to assess the mechanical behavior of WDED titanium samples. This entry won first place in the light microscopy category of the prestigious 2023 International Metallographic Contest.

The 15th World Conference on Titanium included papers on titanium alloy development, efforts to reduce Ti powder costs, additive manufacturing, and computational materials modeling tools. This article reviews some of the key advances reported at the conference.

Among the structural materials developed in the 20th century, titanium and its alloys have played a leading role in improving component performance. This article provides background on the extraction and primary processing of titanium.

Active metal brazing played a key role in the development and fabrication of a modified beam target for particle-physics experiments conducted by Fermilab. The new target consists of a titanium tube filled with stacked graphite fins that were bonded in place by means of active metal brazing. This article describes the vacuum process and the methods used to evaluate the brazed titanium-graphite joints.
