Revisiting Stability Criteria in Ball‐Milled High‐Entropy Alloys: Do Hume–Rothery and Thermodynamic Rules Equally Apply?

open access: yesAdvanced Engineering Materials, Volume 27, Issue 6, March 2025.
The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.

Advanced Powder Shaping Process-MIM.

open access: yesShigen-to-Sozai, 1997
Metal Injection Molding (MIM) process allows fully dense and net shaping of a variety of engineering materials. Therefore, MIM process is hoped to be an advanced powder processing technique to replace the conventional powder metallurgy (P/M) processes for exceeding the proven P/M capabilities.This presentation introduces a few examples of how and what ...

The effect of particle shape on powder properties

open access: yesJournal of Pharmacy and Pharmacology, 1969
Abstract Sand in the size ranges 18–20 mesh, 30–36 mesh and 44–60 mesh has been separated by means of a vibratory shape-sorting table into fractions of different shape. The ratios of the surface area of the particles to their volumes-the shape coefficients-ranged from 8 to 15.

Finite element simulation of powder compaction via shock consolidation using gas-gun system [PDF]

open access: yes
Shock consolidation is a promising method for consolidation of nanocrystalline metallic powders since it can prevent grain growth of nanopowders during the process due to very short processing time.

Characterization of Defect Distribution in an Additively Manufactured AlSi10Mg as a Function of Processing Parameters and Correlations with Extreme Value Statistics

open access: yesAdvanced Engineering Materials, EarlyView.
Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

Effects of initial graphite particle size and shape on oxidation time in graphene oxide prepared by Hummers' method

open access: yesJournal of Science: Advanced Materials and Devices, 2017
The effects of initial graphite particle size and shape on oxidation time of graphite prepared by Hummers' method have been investigated. The oxidation was performed on three series of graphite particles, clod powder with two different sizes of 18 and 6 ...

Experimental Evaluation of 100Cr6 Steel Microindented Surfaces Under Lubricated Nonconformal Point Contacts

open access: yesAdvanced Engineering Materials, EarlyView.
The tribological behavior of 100Cr6 steel spheres textured via Vickers microindentation is evaluated under lubricated sliding by varying both dimple size and density. Fine and dense textures significantly reduce friction across all lubrication regimes, while large dimples increase it.

Investigation of Metal Powder Blending for PBF-LB/M Using Particle Tracing with Ti-6Al-4V

open access: yesJournal of Manufacturing and Materials Processing
Laser-based powder bed fusion of metals (PBF-LB/M) is the most used additive manufacturing (AM) technology for metal parts. Nevertheless, challenges persist in effectively managing metal powder, particularly in blending methodologies in the choice of ...
