Laser surface texturing of TiAl multilayer films—effects of microstructure and topography on friction and wear
(MDPI, 2018-06)
Laser surface texturing is an efficient way to control the friction and wear properties of materials. Although described in many papers, most previous work relates to a pure topographic view of laser-textured surfaces. As ...
Laser surface texturing of tial multilayer films-effects of microstructure and topography on friction and wear
(MDPI AG, 2018)
Laser surface texturing is an efficient way to control the friction and wear properties of
materials. Although described in many papers, most previous work relates to a pure topographic
view of laser-textured surfaces. ...
Isothermal oxidation of Inconel 625 superalloy at 800 and 1000 °C: Microstructure and oxide layer characterization
(2020-03-01)
Superalloys are widely used in applications at high temperatures and severe environments. Inconel 625 is one of the most applied superalloys due to its high oxidation resistance and mechanical properties, however studies ...
Porous cordierite-based ceramics processed by starch consolidation casting – Microstructure and high-temperature mechanical behavior
(Elsevier, 2018-03)
Porous cordierite-based ceramics with different microstructural features and mechanical behavior were formed by starch consolidation casting (SCC) using native potato and corn starches and sintered at 1275, 1300 and 1330 ...
Thermomechanical–microstructural modelling of nodular cast iron solidification
(Taylor & Francis, 2013-11)
This paper presents a thermomechanical–microstructural formulation for the analysis of the solidification process of nodular cast irons of eutectic composition. This formulation is defined in a finite strain thermoplasticity ...
Temperature and stoichiometry effect on microstructural and ferroelectric properties of Pb(Zr1-xTix)O3 thin films prepared by chemical soulution deposition
(2004-05-10)
Lead zirconate titanate (PZT) solutions were prepared using a polymeric precursor method, Zr n-propoxide and Ti i-propoxide were used as starting materials with ethylene glycol and water as solvents. The PZT solution was ...
Ultrasonic sensor signals and optimum path forest classifier for the microstructural characterization of thermally-aged inconel 625 alloy
(2015)
Secondary phases, such as laves and carbides, are formed during the final solidification stages of nickel-based superalloy coatings deposited during the gas tungsten arc welding cold wire process. However, when aged at ...
Effect of doping method on microstructural and defect profile of Sb-BaTiO3
(Elsevier, 2006-06)
Electrical properties in BaTiO3 based ceramics are strongly dependent on composition and microstructural development. In this work, we studied the effect of the particle coating as doping method on microstructure and ...
Sintering of tin oxide processed by slip casting
(2000-12-01)
Sintering of SnO 2 compacts, obtained through slip casting, was studied by means of dilatometry, Hg porosimetry, scanning electron microscopy, and density measurement (Archimedes method). Sintering is strongly influenced ...
