Different Forms of Corrosion Casts [PDF]
, 1994 We have previously described artifacts in corrosion casts prepared with Mercox®, diluted with methylmethacrylic acid (MMA). Using scanning electron microscopy (SEM) of casts and light microscopy (LM) of tissue sections, we found new forms of artifacts in

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

Introduction: Orthodontic diagnosis requires accurate analysis of dental morphology and occlusion. While plaster casts were the standard, several drawbacks such as breakages, storage requirements and retrieval challenges have led to a digital shift ...

, 2010 On the basis of new evidence, this paper will reassess our understanding of the sixteenth-century diffusion of casting from the antique beyond the Alps. In particular, it will raise two points so far underplayed.

Advanced Engineering Materials, EarlyView.Experiments and thermophysical simulations were conducted to investigate the electron beam powder bed fusion electron beam (PBF‐EB/M) process for the γ′‐strengthened nickel‐based superalloy Inconel 738LC. The results demonstrate the impact of process‐induced microstructural variations on high‐temperature mechanical behavior, providing a basis for ...

Advanced Engineering Materials, EarlyView.In situ synchrotron high‐energy X‐ray diffraction reveals the real‐time high‐temperature phase evolution of a ternary V‐9Si‐6.5B alloy. The study uncovers a kinetically delayed V5SiB2 → V8SiB4 transformation governed by massive structural and chemical barriers.

Effects of earthworm casts on crop production
, 2019 Greenhouse and field studies were conducted to determine the effect of earthworm casts on the production of maize and cowpea. In pot experiments with mixtures of soil and casts, shoot and root dry matter (OM) of maize and cowpea increased with increasing

Impact of MgO Additions on the Oxidation Resistance and Compression Behavior of Vanadium Alloys
Advanced Engineering Materials, EarlyView.An increase in oxidation resistance at 600 °C is achieved for alloys containing more than 2.5 wt.% MgO. It has been established that, along with V2O5, MgO6V2, and Mg2O7V2 are formed, which are presumed to enhance oxidative stability. Furthermore, the possible transformation of Mg‐vanadates through reaction with CO2, which presumably occurs in this ...

Rare Adult Case of Plastic Bronchitis in an Otherwise Healthy Adult
Respirology Case ReportsPlastic bronchitis (PB) is characterised by the formation of airway plugs at any level of the respiratory tract. Severe forms of PB can result in airway obstruction. It is more commonly seen in children.
