Advanced Engineering Materials, EarlyView.New features on yttria‐stabilized zirconia after exposure at 1500°C: Newly discovered pyramidal structures on an old material. After exposure at 1550°C on the cross section of YSZ new features, namely pyramidal structures are discovered. These structures grow with time, increase in numbers, appear as singularities, are often arranged in strings, and ...

Surface Tension Measurement of Ti‐6Al‐4V by Falling Droplet Method in Oxygen‐Free Atmosphere
Advanced Engineering Materials, EarlyView.In this article, the temperature‐dependent surface tension of free falling, oscillating Ti‐6Al‐4V droplets is investigated in both argon and monosilane doped, oxygen‐free atmosphere. Droplet temperature and oscillation are captured with one single high‐speed camera, and the surface tension is calculated with Rayleigh's formula.

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.

The thermal stability of the lower atmosphere [PDF]
Proceedings of the Royal Society of London. Series A - Mathematical and Physical Sciences, 1935 Abstract 1—The thermal stability of a layer of incompressible fluid heated below has been investigated by Rayleigh, and Jeffreys. Subsequently Jeffreys J proved that with a small modification the same equation would hold for a compressible fluid.

Advanced Engineering Materials, EarlyView.Identified through the use of statistical design of experiments and metallographic investigation, this study exposes the stochastic origins of intergranular cracks in blown powder laser beam directed energy deposition additive manufacturing of pure molybdenum. It further demonstrates a successful crack mitigation approach with direct correlation to the

On the Dispersion of Gases Discharged to the Chimney of a Thermal Power Plant
The Annals of “Dunarea de Jos” University of Galati. Fascicle IX, Metallurgy and Materials ScienceThis paper presents a theoretical study on the dispersion of gaseous pollutants from a natural gas thermal power plant in the event of a malfunction. Using the Gaussian model, the dispersion of nitrogen oxides generated by such a thermal power plant was ...
