Microstructural examination of the effect of elevated temperature on the concrete containing clinoptilolite
(ELSEVIER SCI LTD, 2014)
In this study, the effect of elevated temperature on the properties of concrete containing clinoptilolite was investigated by microscopic analyses. For this purpose, seven different mixtures were prepared (the control ...
Characterization of a Directionally Solidified Sn-Pb-Sb Ternary Eutectic Alloy
(SPRINGER, 2015)
A Sn-40.5wt%Pb-2.6wt%Sb ternary eutectic alloy was prepared using a vacuum melting furnace and a casting furnace. The samples were directionally solidified at a constant growth rate (V = 16.5 mu m/s) under different ...
Dependency of microindentation hardness on solidification processing parameters and cellular spacing in the directionally solidified Al based alloys
(ELSEVIER SCIENCE SA, 2009)
Al based alloys (Al-0.1 wt.%Ti, Al-05 wt.%Ti and Al-2 wt.%Li) were prepared using metals of 99.99% high purity in the vacuum atmosphere. These alloys were directionally solidified upward with the different temperature ...
Measurements of the microhardness, electrical and thermal properties of the Al-Ni eutectic alloy
(ELSEVIER SCI LTD, 2012)
Al-5.7 wt% Ni eutectic alloy was directionally solidified upward with different temperature gradients (0.83-4.02 K/mm) at a constant growth rate (0.008 mm/s) and with different growth rates (0.008-0.483 mm/s) at a constant ...
A review on micro-level modeling of solid oxide fuel cells
(PERGAMON-ELSEVIER SCIENCE LTD, 2016)

Investigation of the microhardness and the electrical resistivity of undercooled Ni-10 at.% Si alloys
(ELSEVIER SCIENCE BV, 2011)
Ni-10 at.% Si alloys (Ni and Si of purity of 99.99%) were prepared by arc melting method under argon atmosphere in a water-cooled copper hearth with a non-consumable tungsten electrode and titanium getter. Spherical-shaped ...
Effect of rotating magnetic field on the microstructures and physical properties of Al-Cu-Co ternary eutectic alloy
(ELSEVIER SCIENCE SA, 2015)
The solidification microstructures and physical properties of Al-Cu-Co ternary eutectic alloy were studied in a rotating magnetic field (RMF). The RMF-driven flow was the key factor causing grain refinement and uniformity ...
The influence of elevated temperature on strength and microstructure of high strength concrete containing ground pumice and metakaolin
