Characterization of Indium addition on Sn-Bi-Sb Lead free Solder alloy
Journal Title: JOURNAL OF ADVANCES IN PHYSICS - Year 0, Vol 12, Issue 2
Abstract
The aim of these work is to measure the effect of the addition of In with different atomic percent weight on structure, melting, Electrical and mechanical properties of Sn70-X at.% -Bi15 at.% -Sb15 at.%- Inx at.% rapidly solidified. X-ray diffraction analysis (XRD), differential scanning calorimetry (DSC), temperature dependence of resistivity (TDR), and mechanical resonance method are performed. It's found that electrical conductivity (σ) and thermal conductivity (K) increased gradually by increasing In at.%. Melting temperature reduced from 470.12 K for Sn70 at.%- Bi15 at.%- Sb15 at.% to 427.13 K in Sn61 at.%- Bi15 at.%- Sb15 at.%- In9 at.%. Also, elastic moduli, internal friction and thermal diffusivity measured from melt-quenched ribbons.

MAGNETIC FIELD, PRESSURE AND TEMPERATURE DEPENDENT OPTICAL PROPERTIES IN A GaAs 9.0 P 1.0 QUANTUM DOT
Simultaneous effects of magnetic field, pressure and temperature on the exciton binding energies are found in a 9.0 1.0 6.0 4.0 GaAs P / GaAs P quantum dot. Numerical calculations are carried out taking into consideratio...
Correlation between microstructure, mechanical and thermal properties of In-Bi-Sn-Ag melt spun alloys
A series of indium-bismuth-tin-silver alloys containing up to 5 wt. % silver were quenched from melt by chill-block melt-spin technique. The resultant ribbons were studied by X-ray diffraction, scanning electron microsco...

The incredible faculty of perception of the bat is vinculated to their system of ubication by means of eco resonance so; they are oriented by emitting high frequency sounds orientation, and receipting the echoes. In thaw...
Inflections of Periodicities of Background Photon Spectral Power Densities Are Predicted by the Lorentz Contraction for a Potential Indicator for the Intrinsic Structure of Space
The value for the Lorentz contraction to produce a discrepancy for a hypothetical number that reflects a property (21.34) of sub-matter space was calculated. When applied to time the contraction would be ~35 min. T...
