A Method to Determine the Electrical Resistance of a Metallic Powder Mass under Compression
Montes Martos, Juan Manuel; Gómez Cuevas, Francisco de Paula
; Ternero Fernández, Fátima; Astacio, Raquel; Sánchez Caballero, Eduardo; Cintas Físico, Jesús (MDPI, 2017)
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, ... -
High temperature behavior of nanostructured Al powders obtained by mechanical alloying under NH3 flow
Caballero, Eduardo S.; Cintas Físico, Jesús; Gómez Cuevas, Francisco de Paula; Montes Martos, Juan Manuel; Herrera García, M. (American Institute of Physics, 2015)
Aluminium powder was mechanically alloyed under ammonia gas flow for different times (1-5 h) in order to produce a second-phase reinforcement, mainly by aluminium nitride (AlN). After milling, powders were consolidated ... -
In Situ Synthesis of Al-Based MMCs Reinforced with AlN by Mechanical Alloying under NH3 Gas
Caballero, Eduardo S.; Gómez Cuevas, Francisco de Paula; Ternero Fernández, Fátima; Astacio, Raquel; Montes Martos, Juan Manuel; Cintas Físico, Jesús (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, ... -
Influence of Milling Atmosphere on the Controlled Formation of Ultrafine Dispersoids in Al-Based MMCs
Sánchez Caballero, Eduardo; Cintas Físico, Jesús; Gómez Cuevas, Francisco de Paula; Montes Martos, Juan Manuel; Ternero Fernández, Fátima (MDPI, 2016)
Properties of compacts made from aluminium powder, milled under different atmospheres, were evaluated. The duration of all the milling processes was 10 h, although different atmospheres were tested: vacuum, confined ... -
Influence of Temperature on Mechanical Properties of AMCs
Caballero, Eduardo S.; Ternero Fernández, Fátima; Urban, Petr; Gómez Cuevas, Francisco de Paula; Cintas Físico, Jesús (MDPI, 2020-06)
This research focused on studying the effect of temperature on the mechanical properties of aluminium matrix composites (AMCs) obtained by a powder metallurgy route. Aluminium powder was milled at room temperature for 5 ... -
Medium-Frequency Electrical Resistance Sintering of Oxidized C.P. Iron Powder
Montes Martos, Juan Manuel; Gómez Cuevas, Francisco de Paula; Ternero Fernández, Fátima; Astacio, Raquel; Sánchez Caballero, Eduardo; Cintas Físico, Jesús (MDPI, 2018-06)
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 ... -
Medium-Frequency Electrical Resistance Sintering of Soft Magnetic Powder Metallurgy Iron Parts
Astacio, Raquel; Ternero Fernández, Fátima; Cintas Físico, Jesús; Gómez Cuevas, Francisco de Paula; Montes Martos, Juan Manuel (MDPI, 2021)
The fabrication of soft magnetic Fe parts by the medium-frequency electrical resistance sintering (MF-ERS) technique is studied in this paper. This consolidation technique involves the simultaneous application to metallic ... -
Phase stability, porosity distribution and microstructural evolution of amorphous Al50Ti50 powders consolidated by electrical resistance sintering
Urban, Petr; Gómez Cuevas, Francisco de Paula; Montes Martos, Juan Manuel; Cintas Físico, Jesús (American Institute of Physics, 2015)
The effect of intensity and duration of the electrical resistance sintering process on the phase stability, porosity distribution and microstructural evolution of Al50Ti50 amorphous powders is studied. The phase transformations ... -
Production of Ultrafine Grained Hardmetals by Electrical Resistance Sintering
Cintas Físico, Jesús; Astacio, Raquel; Gómez Cuevas, Francisco de Paula; Montes Martos, Juan Manuel; Weissgaerber, Thomas; Lagos, Miguel Ángel; Torres, Yadir; Gallardo, José María (MDPI, 2019)
In this work, powders of cemented ultrafine WC-6 wt.% Co were consolidated. The feasibility of the medium frequency electrical resistance sintering (MF-ERS) technique were studied to prevent WC grain growth during ... -
Simulation of the Electrical Resistance Sintering of Hardmetal Powders
Montes Martos, Juan Manuel; Viña, Francisco J. de la; Agote, Iñigo; Schubert, Thomas; Gómez Cuevas, Francisco de Paula; Torres, Yadir; Gallardo, José María; Cintas Físico, Jesús (Springer, 2019-08)
The simulation of the electrical resistance sintering (ERS) of hardmetal powders has been studied. The ERS process can produce a quick consolidation of electrical conductive powders by the simultaneous application of ...
