Tin-zinc-aluminium alloys for high temperature lead-free solders
Six binary Sn-Zn and fourteen ternary Al-Sn-Zn alloys with 0.6 to 3 wt.% Al were prepared experimentally. The alloys were studied metallographically. The micro-hardness and X-ray micro-analysis (EDAX,WDX) of the phases was measured. Temperatures and latent heats of characteristic phase transitions (liquidus,solidus,invariant reactions etc.) were obtained with use of the DTA meth od.Experiments were performed with Setaram SETSYS 18_TM experimental laboratory system for thermal analysis.Samples of selected al loys were analysed at linear heating/cooling rate of 4 ?/min in high pure atmosphere of argon.Resulting experimental data were com pared with data of known Sn-Zn binary system and al-Sn-Zn ternary system.For the modelling of phase equilibria from critically assessed data software packages were used;MTDATA,PANDAT and Thermo-Calc.
