Tomographic characterization of copper cellular bodies fabricated by a powder metallurgy route
(Institute of Physics Publishing, 2019-02-13)
Copper cellular bodies were prepared by powder metallurgy employing carbamide beads as space holders, which were removed by water dissolution before sintering the compact. The method allows for a precise control of the ...
Ancient metalworking in South America: A 3000-year-old copper mask from the Argentinian Andes
(Cambridge University Press, 2017)
Metallurgy in pre-Columbian America first developed in the Andes, and Peru has long been considered to be the initial point of origin. The recent discovery of an anthropomorphic copper mask in north-west Argentina, however, ...
Immigrants métallurgistes français et vitiviniculture modern à Mendoza et San Juan, Argentine (1885-1930)The metallurgical French immigrants in the origins of the wine model of Mendoza and San Juan, Argentine (1885-1930)
(Presses universitaires de Bordeaux, 2007-12)
L’étude trace un panorama sur le rôle accompli par un groupe, réduit mais actif, d’immigrants métallurgistes français, aux origines du modèle vitivinicole de Mendoza et San Juan, deux provinces situées au Centre-Ouest du ...
Titanium-hydroxyapatite composites sintered at low temperature for tissue engineering: In vitro cell support and biocompatibility
(Wichtig Publishing Srl, 2017-04)
In clinical orthopedics, a critical problem is the bone tissue loss produced by a disease or injury. The use of composites from titanium and hydroxyapatite for biomedical applications has increased due to the resulting ...
The Microstructure and the Phase Stability of a Cu–30at.%Al Alloy Obtained by Reactive Milling and Quenching
(Springer, 2020-12)
The phase stability of a Cu–30at.%Al milled and quenched is studied by differential scanning calorimetry and in situ high-temperature X-ray diffraction (HT-XRD). This analysis was performed from room temperature to 700 °C. ...
Pre-Columbian metallurgy – Evidence of pyrotechnical ceramics from Rincón Chico, Northwestern Argentina (Andes)
(Elsevier Ltd, 2018)
An assemblage of 16 fragments of pyrotechnical ceramics used for metallurgical processing was examined by scanning electron microscopy (SEM). The ceramics came from Rincón Chico in the Andes Region of Northwestern Argentina. ...

(Societé des Américanistes, 2021-12)
This paper approaches the Swedish Chaco-Cordillera Expedition to the North of Argentina and South of Bolivia (1901-1902) and it focuses on the archaeological objects recovered. Besides the analysis performed by Eric von ...
Wear analysis of PM compacts with bainitic microstructures, under unlubricated sliding conditions
(Elsevier, 2015-06-02)
Ferrous and non-ferrous alloys can be processed by PM. Complex shapes and good surface finishes can be achieved, leading to promising applications, if mechanical properties are demonstrated to be high enough. At the same ...
