Characterization of phase changes during fabrication of copper alloys, crystalline and non-crystalline, prepared by mechanical alloying
(Universidad Nacional de Colombia - Sede Bogotá - Facultad de Ingeniería, 2016-09-01)
The manufacture of alloys in solid state has many differences with the conventional melting (casting) process. In the case of high energy milling or mechanical alloying, phase transformations of the raw materials are ...
Caracterización estructural de la transición de fase del intermetálico Al2Cu durante la molienda mecánica de alta energía
(Universidad Michoacana de San Nicolás de Hidalgo, 2012-02)
The present research is related to the high energy mechanical milling (MM) process of the inter alloy Al 2 Cu at different times. This process is characterized by an out-of-equilibrium processing, which consists in the ...
Platinum-Group Minerals in Chromitites of the Niquelandia Layered Intrusion (Central Goias, Brazil): Their Magmatic Origin and Low-Temperature Reworking during Serpentinization and Lateritic Weathering
(Mdpi Ag, 2012-12-01)
A variety of platinum-group-minerals (PGM) have been found to occur associated with the chromitite and dunite layers in the Niquelandia igneous complex. Two genetically distinct populations of PGM have been identified ...
Polymeric precursor method to the synthesis of XWO(4) (X = Ca and Sr) thin films-Structural, microstructural and spectroscopic investigations
(Elsevier B.V. Sa, 2009-05-27)
Stoichiometric XWO(4) (X = Ca, and Sr) thin films were synthesized using the polymeric precursor method. In this soft chemical method, soluble precursors such as strontium carbonate, calcium carbonate and tungstic acid, ...

Deposição e caracterização de revestimentos de Ni-Ti e Ni-Ti/Nb para aplicações biomédicas
(Pontifícia Universidade Católica do Rio Grande do SulPorto Alegre, 2007)
Among all kinds of shape memory alloys, NiTi are probably the most important and used due to its improved mechanical and tribological properties. Bulk NiTi alloys are widely applied as biomedical materials and in diverse ...

Characterization of photochemically grown Pd loaded WO3 thin films and its evaluation as ammonia gas sensor
(Elsevier, 2020)
Pd-loaded tungsten oxide thin films have been successfully fabricated by direct UV irradiation of bis(beta-diketonate)dioxotungsten(VI) and Pd(II) precursor complexes spin-coated on Si(100) substrates. X-ray diffraction ...
