Determination of Solidification of Rigidity Point Temperature Using a New Method [PDF]

, 2020
This work aims to calculate the rigidity point temperature of aluminum alloys by three new methods and compare them with currently employed methods. The influence of major and minor alloying elements over the rigidity point temperature is also discussed.

Optimizing casting process using a combination of small data machine learning and phase-field simulations

npj Computational Materials
It has been a challenge to employ machine learning (ML) to optimize casting processes due to the scarcity of data and difficulty in feature expansion. Here, we introduce a nearest neighbor search method to optimize the stratified random sampling in Latin

Oxidation behaviors of a Ni–Cr–W based superalloy with different microstructures

Journal of Materials Research and Technology
Oxidation behaviors of a Ni–Cr–W based superalloy were investigated in terms of microstructural characteristics. It was found that the specimens with small grains present a better oxidation resistance owing to their higher density of grain boundaries ...

Phase-field modeling and Experimental investigation for rapid solidification in wire and arc additive manufacturing

Journal of Materials Research and Technology
The rapid solidification speed and significant temperature gradient observed in the wire and arc additive manufacturing (WAAM) process result in a deviation of the solid-liquid interface from the equilibrium state assumed by the conventional directional ...

Possibilities and Limitations of Scanning Electrochemical Microscopy of Mg and Mg Alloys [PDF]

Corrosion, 2014
Magnesium (Mg) and its alloys undergo corrosion at high rates in aqueous electrolytes of essentially any concentration, releasing copious amounts of hydrogen (H2) into the electrolyte, thereby making conventional scanning electrochemical microscopy (SECM) measurements difficult upon Mg.

Band-gap bowing and p-type doping of (Zn, Mg, Be)O wide-gap semiconductor alloys: a first-principles study

, 2008
Using a first-principles band-structure method and a special quasirandom structure (SQS) approach, we systematically calculate the band gap bowing parameters and \emph{p}-type doping properties of (Zn, Mg, Be)O related random ternary and quaternary ...

Phase-field simulation for anisotropic dendrite growth in Mg-3wt.%Zn alloy

Journal of Materials Research and Technology
The anisotropy interfacial energy changes the growth tendency of dendrites in different directions during solidification, when the growth tendency in a specific direction appears or disappears, the transition of dendrite orientation will happen.
