Electrical resistivity measurement to predict uniaxial compressive and tensile strength of igneous rocks
(INDIAN ACAD SCIENCES, 2010)
Electrical resistivity values of 12 different igneous rocks were measured on core samples using a resistivity meter in the laboratory. The resistivity tests were conducted on the samples fully saturated with brine (NaCl ...
Determination of mechanical, electrical and thermal properties of the Sn-Bi-Zn ternary alloy
(ELSEVIER SCIENCE BV, 2011)
The development of lead-free solders has emerged as one of the key issues in the electronics packaging industries. Sn-Zn-Bi eutectic alloy has been considered as one of the lead-free solder materials that can replace the ...
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 ...
Variations of microhardness with solidification parameters and electrical resistivity with temperature for Al-Cu-Ag eutectic alloy
(ELSEVIER SCIENCE BV, 2012)
Al-Cu-Ag eutectic alloy was directionally solidified upwards with different growth rates (1.83-498.25 mu m/s) at a constant temperature gradient (8.79 K/mm) and with different temperature gradients (3.99-8.79 K/mm) at a ...
Investigation of the Some Physical Properties of the Directionally Solidified Al-Cu-Co Ternary Eutectic Alloy
(SPRINGER INDIA, 2015)
The Al-23.9% Cu-1.2% Co (wt%) ternary eutectic alloy was prepared using a vacuum melting furnace and a casting furnace. The samples were directionally solidified upwards at a constant growth velocity (18.8 mu m/s) under ...
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 ...
Microstructural, mechanical, electrical and thermal characterization of arc-melted Ni-Si and Co-Si alloys
(ELSEVIER SCIENCE BV, 2010)
This work presents the results of characterization of as solidified arc-melted Ni-Si and Co-Si alloys. The alloys of different compositions of the constitutions Ni, Co, and Si of purity of 99.99% were prepared by arc melting ...
Dependency of structure, mechanical and electrical properties on rotating magnetic field in the Bi-Sn-Ag ternary eutectic alloy
(CARL HANSER VERLAG, 2016)
In the present study, cylindrical samples of the Bi-Sn-Ag ternary eutectic alloy were exposed to a rotating magnetic field (RMF) during upward solidification. The dependence of the eutectic spacing (lambda), microhardness ...
Investigation of the effect of composition on microhardness and determination of thermo-physical properties in the Zn-Cu alloys
(ELSEVIER SCI LTD, 2011)
Zinc-copper of (99.99%) high purity alloys were directionally solidified upward with different compositions, C-o, Zn-(0.7,1.5, 2.4 and 7.37) wt.% Cu under two different solidification conditions (G = 3.85 K/mm, V = 0.0083 ...
