Investigation of Selected Thermo-physical Properties of Ternary Sn-Zn-Al Alloys Using DTA
Result description
The paper deals with the investigation of temperatures and latent heats of phase transformations of two binary alloys Sn-Zn and five ternary Sn Zn Al alloys using the DTA method. The investigated alloys belong to the area of the so called eutectic "valley" of the Sn-Zn-Al system. DTA of investigated samples was performed at the rate of heating/cooling of 4°C/min. In this way there were obtained temperatures of phase transformations of the ternary system Sn-Zn-Al, temperature of ternary eutectics TE1 197.6°C, temperature of liquidus, and other transformations. Latent heats of melting and solidification were calculated. Latent heat of melting of alloys varies within the interval 71-91 J.g-1, solidification within the range 73-99 J.g-1. Theoretical isoplethic phase diagrams were created with use of the software MTData and Pandat. Experimental data were compared with the calculated temperatures.
