The relation between valency, axial ratio, Young's modulus and resistivity of rapidly solidified tin-based eutectic alloys

摘要

Eutectic alloys of Sn with Cu, Cd, Al, Pb and Sb (peritectic) were produced by the melt-spinning technique. These alloying elements were chosen according to their valencies +1, +2, +3, +4 and +5 respectively. X-ray diffraction analysis (XRD) was carried out. Young's modulus and resistivity were measured. It was found that, alloying Sn with low valency metals such as Cu and Cd increases the axial ratio and alloying Sn with high valency metals such as Pb, Sb and Bi decreases the axial ratio. Also Young's modulus was found to increase by increasing the axial ratio and decreases by decreasing it. On the contrary the resistivity decreases by increasing the axial ratio.
