The effect of rapid solidification on the structure, decomposition behavior, electrical and mechanical properties of the Sn-Cd binary alloys

A group of rapidly solidified Sn-Cd alloys has been prepared by a melt-spinning technique. X-ray diffraction, microstructure, and differential thermal analysis have been carried out. Young's modulus and internal friction have been measured, and the temperature dependence of resistivity has been evaluated. The results show a modification in both the microstructure and decomposition behavior. Also, an interesting connection between Young's modulus and the axial ratio (c/a) of the unit cell of the beta-Sn was found in which Young's modulus increases by increasing the axial ratio (c/a). It was found also that the internal friction increases on increasing the Cd concentration. (C) 2004 Kluwer Academic Publishers.
