TL;DR: In this paper, a nanocrystalline surface layer was fabricated on a 38CrMoAl steel plate by means of a surface mechanical attrition treatment (SMAT), and the average grain size in the top surface layer (10 pm thick) is about 10 nm, and the grain size stability can be maintained up to 450 degrees C. The results of the investigation showed that this new gas nitriding technique can effectively increase the hardness and wear resistance of the resulting surface layer in comparison with conventional gas n-riding, demonstrating a significant advancement for materials processing.

TL;DR: In this article, the sliding wear resistance of a nanostructured spheroidal steel varies with grain size: it increases when the grain size of the ferrite phase (Dα) increases from 8 to 32, and decreases with a further increase in Dα.

TL;DR: In this article, the wear volume of Cu-Al alloys decreases with an increasing Al content below 0.5 Wt, and increases with higher Al contents above 0.2 Wt.

TL;DR: In this paper, the authors investigated total ionizing dose effects on the electrical characteristics of HfO2/Hf-based bipolar resistive-random access memory (RRAM) devices.

TL;DR: The sliding wear resistance of Cu-2.2 wt.% Al alloy can be remarkably enhanced by controlling subsurface dynamic recrystallization (DRX) process as discussed by the authors.
