Thermomechanical Fatigue and Creep–Fatigue Interaction of Inconel 718 Additively Manufactured by Laser Beam Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

ESTIMATION OF MAXIMUM ACTIVE POWER TRANSMISSION TO LOAD FOR ACTIVE MULTI-POLAR DEVICES

Известия высших учебных заведений и энергетических объединенний СНГ: Энергетика, 2005
The paper considers problems of matching irreversible multi-polar circuits loaded to active multi-polar devices because power to be transmitted is maximal under such conditions.

Low‐Angle Grain Boundaries and Re‐Segregation in Single‐Crystalline Ni‐Base Superalloys

Advanced Engineering Materials, EarlyView.
This work demonstrates that Re‐segregation at low‐angle grain boundaries (LAGBs) in Ni‐base superalloys is influenced by misorientation angle. Advanced microscopy and atom probe tomography reveal that higher misorientation angles increases Re‐segregation.

Optimization of Normal Regimes of Power Transmission Lines

Известия высших учебных заведений и энергетических объединенний СНГ: Энергетика, 2006
In order to optimize normal regimes of the power transmission lines notions of economic, maximum and the largest efficiency of a transmission line are used. Power losses by wire corona transmission losses are considered.

Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading

Advanced Engineering Materials, EarlyView.
The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.
