Single‐Pulse Nanomorphology Governs Laser‐Induced Periodic Surface Structure Formation on Metals
Laser &Photonics Reviews, EarlyView.Ultrashort pulse ablation enables generation of self‐organized periodic structures, where evolving nanomorphology controls pulse‐to‐pulse feedback. In noble metals, nanospikes form after the first pulse and localize surface waves, preventing periodic field distributions and thus suppressing their formation.

Materials and Corrosion, EarlyView.Cr‐alloyed quenched and tempered prestressing steel wires were found to be as highly susceptible as non‐Cr‐alloyed ones. This finding is in contrast to the known literature. A newly developed and reproducible method for assessing susceptibility to hydrogen‐induced stress corrosion cracking was used.

Materials and Corrosion, EarlyView.Application of centrifugally cast alloys during Ammonia Cracking in ammonia containing atmospheres at high temperatures (up to 900°C) induces corrosion by means of nitridation. The mechanisms of material degradation are not reliably understood yet. This article focuses on the identification of corrosion mechanisms for Cr‐Ni‐Fe‐ and Cr‐Ni‐Fe‐Al cast ...

Materials and Corrosion, EarlyView.The findings presented in this manuscript recommend the Ti‐22Zr‐11Nb‐2Sn alloy as a possible alternative to Nitinol for use in biomedical devices, especially in the large‐scale manufacturing of self‐expandable vascular stents used in angioplasty. ABSTRACT Nowadays, for applications such as coronary stents, the most widely used materials are Nitinol or ...

Materials Genome Engineering Advances, EarlyView.Bipolar electrochemistry enables high‐throughput investigation of gravity's effect on pitting corrosion in stainless steel (type 304L/420). By varying specimen orientation, significant gravity‐induced changes in pit nucleation, propagation, and morphology are observed on the bipolar electrodes across a wide range of applied potentials. Abstract Bipolar

steel research international, EarlyView.On the pathway to climate‐neutral steel production, recycling fractions will necessarily increase over time. Since alloying elements will enrich progressively, as they cannot be removed economically from the melt, processes need to be adjusted.

steel research international, EarlyView.In this study, the susceptibility to copper‐induced hot shortness of the alloy 42CrMo4 is investigated by different hot tensile tests, as well as by a detailed analysis of the formed oxidation products. While an enrichment of metallic copper and a penetration of the grain boundaries are observed, no critical reduction of the tensile test properties can

Effect of sub-zero cooling on microstructure and mechanical properties of a low alloyed austempered ductile iron [PDF]
China Foundry, 2007 The effect of sub-zero cooling on microstructure and mechanical properties of a low alloyed austempered ductile iron has been investigated. Austempering of samples was performed at 325! and 400℃ after austenitizing at 875℃ and 950℃.
