Electrical and microstructural properties of superconducting MgB 2/Mg composites
(Trans Tech Publications, 2004)
MgB2/Mg composites were prepared to improve mechanical properties of brittle superconducting MgB2. MgB2 and Mg powders were mixed at different weight ratios and uniaxially pressed in a cylindrical dye at 0.5 GPa and at ...
Electrical and mechanical properties of superconducting MgB2/Mg metal matrix composites
(IOP Publishing, 2006)
MgB2/Mg composites were prepared using a metal matrix composite fabrication method that offers the potential to produce superconducting wires as an alternative approach to the powder in tube process. To obtain composites, ...
Temperature dependence of electrical conductivity in double-wall and multi-wall carbon nanotube/polyester nanocomposites
The aim of this study is to investigate temperature dependence of electrical conductivity of carbon nanotube (CNT)/polyester nanocomposites from room temperature to 77 K using four-point probe test method. To produce ...
Strain gauges of GaSb-FeGa1.3 eutectic composites
A needle-shaped metallic FeGa1.3 phase oriented in a specific direction and uniformly distributed within a GaSb matrix was grown by a vertical Bridgman method. Strain-gauge characteristics, such as strain-sensitivity ...
Features of electron and phonon processes in GaSb-FeGa1.3 eutectics
(IOP Publishing, 2003-11)
Eutectic alloys of GaSb-FeGa1.3 were prepared by the vertical Bridgman method. A microstructure with the needle-shaped metallic FeGa1.3 phase oriented in a specific direction and uniformly distributed within the GaSb matrix ...
Thermostable tensoresistors of Co doped GaSb-FeGa1.3 eutectic composites
The microstructure and tensoresistive properties of GaSb-FeGa1.3 eutectic composites doped with 0.1% Co have been investigated. It was found that the Co impurity atoms mainly accumulate in the metallic inclusions. The ...
