| Abstract | ||
| A study of the microaddition dependence of the structural, mechanical and electrical characteristics of lead-5wt.% Sn alloy prepared by melt spinning and/or the conventional method was carried out using X-ray diffraction, dynamic resonance technique, hardness and resistivity measurements. The conventional method produced more crystalline structure than that of the melt spun. The thermal diffusivity, hardness and resistivity values were found to be higher for PbSn samples prepared by the conventional method than those of the melt spun PbSn samples, while the value of the internal friction was higher for the melt-spun alloy samples. This may be due to the creation of defects by the rolling process used during the preparation of the cold rolled sheets. The dynamic Young’s modulus was nearly of the same order for both the rapidly solidified and the cold rolled alloys. The results were explained in terms of the dislocation theory, the effect of quenching rate on the produced density fluctuations in composition and the modes of interaction of crystal lattice defects. | ||
