Microstructure of the microalloyed NiAl-V eutectics
(Elsevier Science BvAmsterdamHolanda, 2002)
Sensitivity of the thermomechanical response of elastic structures to microstructural changes
(Pergamon-Elsevier Science Ltd, 2015-07)
This paper is focused on the analysis of the sensitivity of the thermomechanical response of a macroscopic elastic body to changes that occur at the microstructure. This problem is a key issue in material design. The ...
Microstructure and texture of duplex stainless steel after melt-spinning processing
(ELSEVIER SCIENCE INC, 2008)
The microstructure and texture of melt-spun UNS S31803 (DIN W. Nr. 1. 4462) duplex stainless steel were analyzed after casting and solution treatment. The cast ribbons contained austenite (gamma) and ferrite (alpha or ...
Influence of the microstructure in the collapse of a residual clayey tropical soil
(SPRINGER HEIDELBERG, 2009)
A typical residual clayey soil originating from basalt in southern Brazil has been analyzed in order to assess the influence of wetting-induced deformation and microstructural features on the collapse behavior. Single and ...
The role of oxygen vacancies on the microstructure development and on the electrical properties of SnO2-based varistors
Variations on the microstructure development and on the electrical properties of SnO2-based varistors are discussed on the basis of the oxygen vacancies created or annihilated by the presence of different additives. Electron ...
Microstructural investigation of the PZT films prepared from the suspension of nanocrystalline powders
(Elsevier B.V., 2004-01-01)
PZT thin films of composition Pb(Zr0.52Ti0.48)O-3 were prepared by a novel method from the suspension of nanocrystalline PZT powders. The powders were obtained by mechanochemical synthesis. Films were deposited on silicon ...
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. ...
Laser surface texturing of TiAl multilayer films—effects of microstructure and topography on friction and wear
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 ...
Microstructure evolution during warm deformation of low carbon steel with dispersed cementite
The microstructure evolution and mechanical behavior during large strain of a 0.16%C-Mn steel has been investigated by warm torsion tests. These experiments were carried out at 685°C at equivalent strain rate of 0.1 s . ...
The influence of the sintering system on PMN properties
PMN powder samples with PbO excess of 0, 1,2 and 3% were submitted to the pressing and sintering at 1200°C for 4h with a heating rate of 3°C/min. A new sintering system, developed at our laboratories, was used. It allows ...
