Consolidation by MF-ERS of mechanically alloyed Al powder
(Elsevier, 2019-07)
The aim of this work is to study the viability of producing, by medium-frequency electrical resistance sintering (MF-ERS), compacts from mechanically alloyed aluminium powders. The MF-ERS process was carried out using ...

In Situ Synthesis of Al-Based MMCs Reinforced with AlN by Mechanical Alloying under NH3 Gas
(MDPI, 2018)
Aluminum matrix composites (AMCs) reinforced by aluminum nitride were prepared by mechanical alloying followed by a simple press and sintering method. Milling began under vacuum and after a period of between 1 and 4 h, ...

Medium-frequency electrical resistance sintering of oxidized C.P. iron powder
(MDPI, 2018)
Commercially pure (C.P.) iron powders with a deliberate high degree of oxidation were consolidated by medium-frequency electrical resistance sintering (MF-ERS). This is a consolidation technique where pressure, and heat ...

A Method to Determine the Electrical Resistance of a Metallic Powder Mass under Compression
(MDPI, 2017-11-06)
In this paper, a phenomenological model to predict the value of the electrical resistance of a compressed metal powder mass is proposed. The model, based on the experimental compressibility and resistivity-porosity curves, ...
