Plasma Surface Metallurgy of Materials Based on Double Glow Discharge Phenomenon [PDF]
arXiv, 2020 Plasma Surface Metallurgy/Alloying is a kind of surface metallurgy/alloying to employ low temperature plasma produced by glow discharge to diffuse alloying elements into the surface of substrate material to form an alloy layer. The first plasma surface metallurgy technology is plasma nitriding invented by German scientist Dr.

Digital Methods for the Fatigue Assessment of Engineering Steels
Advanced Engineering Materials, EarlyView.The use of engineering steels is often limited by their fatigue strength. In the sake of a faster product development, the fatigue behavior can be predicted by machine learning (ML). In this work, ML is applied on a heterogeneous database, covering a wide range of steel types.

Nondestructive Quality Control in Powder Metallurgy using Hyperspectral Imaging [PDF]
arXiv, 2022 Measuring the purity in the metal powder is critical for preserving the quality of additive manufacturing products. Contamination is one of the most headache problems which can be caused by multiple reasons and lead to the as-built components cracking and malfunctions.

From Damage to Functionality: Remanufacturing of Thrust Roller Bearings by Tailored Forming
Advanced Engineering Materials, EarlyView.Herein, the wear and fatigue behavior of repaired bearing raceways with a new powder alloy is investigated using a FE8 test‐rig and an oscillating tribometer. The tests are compared with industrial manufactured bearings to evaluate the repair quality. The repair can extend the service life of the repaired bearing to that of a new bearing and improves ...

Deformation Mechanisms in High Entropy Alloys: A Minireview of Short-Range Order Effects [PDF]
arXiv, 2023 The complex atomic scale structure of high entropy alloys presents new opportunities to expand the deformation theories of mechanical metallurgy. In this regard, solute-defect interactions have emerged as critical piece in elucidating the operation of deformation mechanisms.

Nature, 1899 BERGRATH DR. CARL SCHNABEL is professor of metallurgy and chemical, technology at the Royal Academy of Mines at Clausthal, and his work has long enjoyed a well-deserved reputation. Prof. Henry Louis, who translates it, points out that it is a curious fact that there does not exist in the English language a single complete treatise on metallurgy.
