Özet

Alumix-431 materials were prepared by cold and warm compaction method applying 350-400 MPa pressures at RT (room temperature) 50 and 80°C temperatures. The density measurements of materials were performed; the thermoelectric properties of materials were investigated at 5-300K under the He atmosphere, and the relationship between the measurements and sample properties was examined. The measurements of thermoelectric properties showed that maximum resistivity [Alumix -431-1] and thermal conductivity [Alumix -431-6] values were obtained 0.161Ωm and 24.31W/Km, respectively at 285-295K temperature ranges and minimum electrical resistivity and thermal conductivity values were obtained on Alumix-431-6 and Alumix-431-1 samples, respectively. It was observed that Seebeck coefficient values varied mostly from negative sign to positive sign indicated dominate from carriers. The maximum Figure of merit value was determined as 18.71×10-2; on the Alumix-431-5 alloy at 96.904K

Abstract

Alumix-431 materials were prepared by cold and warm compaction method applying 350-400 MPa pressures at RT (room temperature) 50 and 80°C temperatures. The density measurements of materials were performed; the thermoelectric properties of materials were investigated at 5-300K under the He atmosphere, and the relationship between the measurements and sample properties was examined. The measurements of thermoelectric properties showed that maximum resistivity [Alumix -431-1] and thermal conductivity [Alumix -431-6] values were obtained 0.161Ωm and 24.31W/Km, respectively at 285-295K temperature ranges and minimum electrical resistivity and thermal conductivity values were obtained on Alumix-431-6 and Alumix-431-1 samples, respectively. It was observed that Seebeck coefficient values varied mostly from negative sign to positive sign indicated dominate from carriers. The maximum Figure of merit value was determined as 18.71×10-2; on the Alumix-431-5 alloy at 96.904K
