Formação de grãos ferríticos ultrafinos através de transformação de fase induzida por deformação
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEM, 2007-10-26)
One of the key points in steel development has been the refinement of the microstructure, however without change the chemical composition with addition of alloy elements. The refinement of the ferrite grain size leads ...
Silver colloidal nanoparticles by electrochemistry: temporal evaluation and surface plasmon resonance
(Journal of Physics: Conference Series, 2021-10-18)
The electrochemical technique for obtaining silver nanoparticles has advantages over other methods. For the synthesis, a colloidal silver generator (Colloidal Silver Generator® model 1001) was used, where two electrodes ...
Wear and corrosion behaviour of Al2O3-TiO2 coatings produced by flame thermal projection
(Journal of Physics: Conference SeriesBogota , Colombia, 2017-12-29)
Evaluated the wear resistance and the coatings corrosion behaviour of Al2O3-TiO2 prepared by thermal spraying by flame on AISI 1020 carbon steel substrates, previously coated with an alloy base Ni. For this purpose, were ...
Effect of Retained Austenite and Non-Metallic Inclusions on the Mechanical Properties of Resistance Spot Welding Nuggets of Low-Alloy TRIP Steels
(MDPI, 2019-09-30)
The combination of high strength and formability of transformation induced plasticity (TRIP)
steels is interesting for the automotive industry. However, the poor weldability limits its industrial
application. This paper ...

Ceramics for dental restorations – an introduction
(Universidad Nacional de Colombia Sede Medellín, 2010)
Dental ceramics are the preferred materials for oral restoration due to some characteristics, such as adequate esthetics, high fracture strength and chemical stability. Currently, dental professionals have a large amount ...
Preferential solvation of xylitol in ethanol + water co-solvent mixtures according to the ikbi and qlqc methods
(Universidad Nacional de Colombia, 2013)
The preferential solvation parameters, i.e., the differences between the local around the solute and bulk mole fractions of the solvents in solutions of xylitol in ethanol + water binary mixtures are derived from their ...
