Abstract
In this paper, the microstructure and thermal behavior of two rapidly solidified of eutectic Indium-Bismuth and Indium-Bismuth-Tin Field’s metal are reported. This work experimentally measures the specific heat of the eutectic alloys of the binary Indium-bismuth and indium –bismuth –tin tertiary system using a differential scanning calorimeter (DSC) technique and analyzes the results to determine the thermodynamic properties of the system have sufficient scaling for experimental modeling applications. The resultant ribbons were studied by X-ray diffraction (XRD), scanning electron microscope (SEM) techniques, energy dispersive x-ray (EDX) technique. From the differential scanning calorimetry measurements, it is found that entropy change, enthalpy and specific heat are improved and enhanced compared with literature. The electrical resistivity was reported for temperatures between 295 and 330 K for all the melt-quenched ribbons of binary In-49Biand tertiary In-32.5 Bi -16.5 Sn (wt.%). The microhardness, elastic moduli, internal friction and both thermal diffusivity and thermal effusivity were also measured. Field’s metal is more than suitable for use in experimental settings as it is non-reactive, non-toxic, simple to manufacture, easy to use, and responds to a magnetic force.
