Influence of aging on microstructure and hardness of lead-free solder alloys
(Emerald, 2021-01-08)
Purpose: The purpose of this paper is to carry out a study of the evolution of the microstructure and the microhardness of Sn-Cu-Ag alloys from as-cast condition and under artificial isothermal aging at different temperatures ...
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 ...
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 ...
The role of oxygen vacancies on the microstructure development and on the electrical properties of SnO2-based varistors
(Springer, 2005-03-01)
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 and electrochemical study of La0.5Li0.5TiO3
(Elsevier B.V. Sa, 2011-05-16)
The La0.50Li0.50TiO3 powder was synthesized by the polymeric precursor method. The thermal evolution of the precursor powder heated from 350 degrees C to 700 degrees C was followed by means of Raman spectroscopy. The ...
Microstructure of doped barium titanate prepared from polymeric precursors
(2002-12-01)
Barium titanate is used extensively as a dielectric in ceramic capacitors, particularly due to its high dielectric constant and low dielectric loss characteristics. It can be made semiconducting by addition of certain ...
