Abstract Nanocrystalline materials are known to possess excellent radiation resistance due to high fraction of grain boundaries that act as defect sinks, provided they are microstructurally stable at such extreme conditions. In this work, radiation response of a stable nanocrystalline Cu-Ta alloy is studied by irradiating with 4 MeV copper ions to doses (close to the surface) of 1 displacements per atom (dpa) at room temperature (RT); 10 dpa at RT, 573 and 723 K; 100 and 200 dpa at RT and 573 K....

This paper focuses on the mechanisms of phase transformations in additively manufactured Ti–6Al–4V during cooling. In particular, the goal is to understand if the imposed thermal cycles during fabrication results in the complete transformation of the α′ to the β phase or the sub-transus decomposition of α′ (martensite) to α + β. To this effect, samples fabricated using electron beam melting and laser-directed energy deposition techniques were analyzed using atom probe tomography (APT) in conjunc...

Abstract This paper focuses on the precipitates found in the 300 grade maraging steel built by Selective Laser Melting (SLM), which is globally one of the fastest-growing Additive Manufacturing (AM) technology. The test samples were built layer by layer via full melting and rapid solidification of the deposited powder bed of 300 grade maraging steel, using an M2 Concept Laser machine. The samples were aged at 510 °C for 2 h, and then air-cooled. Optical microscopy, scanning electron microscopy, ...
