Advanced Engineering Materials, EarlyView.High‐temperature interactions between low‐sulfur Al‐killed Mn–B steel and MgO–C refractories (0 and 50 wt% recyclates) are studied via finger immersion tests (1600 °C). Surface‐active elements influence infiltration. MgO/CaS layer forms, along with spinel and calcium silicate.

900 V GaN-based sine-wave inverters for three-phase industrial applications
The Journal of Engineering, 2019 GaN devices are gradually getting attention within the industry along with SiC as a potential wide bandgap device. At present, there are almost no high-voltage GaN devices with voltage >650 V, which makes an inverter design difficult for a three-phase ...

Advanced Engineering Materials, EarlyView.The thermal diffusivity of MgO‐C refractories is highly sensitive to sample preparation and processing procedures. In this article, the effects of coking sequence, machining conditions, structural inhomogeneity, and graphite coating application on measurements using laser flash apparatus are systematically investigated.

Laser Metal Powder Deposition of Titanium Microalloyed HSLA Steel FeC0.12Si0.25Mn1.3
Advanced Engineering Materials, EarlyView.This study investigates the additive manufacturing of titanium‐doped high‐strength low‐alloy (HSLA) steel via laser metal deposition. It reveals distinct process‐structure relationships for elemental powder blends compared to prealloyed feedstocks.

Design of a full SiC three-phase power factor correction with an interleaved output buck converter
The Journal of Engineering, 2019 Active rectification of the three-phase grid nowadays is a central task of power electronics. However, as the necessary DC bus voltages vary, DC-DC converters are needed.

Advanced Engineering Materials, EarlyView.High‐frequency (HF) welding of steel is limited by oxide inclusions that degrade weld quality. This study demonstrates, for the first time, the integration of a nonthermal Ar/H2 dielectric barrier discharge (DBD) plasma jet into HF welding. Local plasma treatment provides effective shielding and in‐situ oxide reduction, resulting in markedly fewer and ...
