Amorphous Al-Ti Powders Prepared by Mechanical Alloying and Consolidated by Electrical Resistance Sintering
Urban, Petr; Ternero Fernández, Fátima; Caballero, Eduardo S.; Nandyala, Sooraj; Montes Martos, Juan Manuel; Gómez Cuevas, Francisco de Paula
(MDPI, 2019-10)
A novel processing method for amorphous Al50Ti50 alloy, obtained by mechanical alloying and subsequently consolidated by electrical resistance sintering, has been investigated. The characterisation of the powders and the ... -
Consolidation of iron powder by electrical discharge
Aranda Louvier, Rosa María; Ternero Fernández, Fátima; Astacio, Raquel; Urban, Petr; Gómez Cuevas, Francisco de Paula (Elsevier, 2022-07-25)
Capacitor electrical discharge consolidation (CEDC) is a technique that uses the heat of the Joule effect of a high intensity electric current to consolidate powders. In this study, the effect of the precompaction pressure ... -
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 ... -
Influence of the Total Porosity on the Properties of Sintered Materials—A Review
Ternero Fernández, Fátima; Guerra Rosa, Luís; Urban, Petr; Montes Martos, Juan Manuel; Gómez Cuevas, Francisco de Paula (MDPI, 2021-04)
Porosity is a characteristic present in most sintered materials, full densification only being achieved in special cases. For some sintered materials, porosity is indeed a desired characteristic, serving for the intended ... -
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 ...
