“…The fabrication of lead-free solders by the vacuum melting process is now widely used to improve the wetting characteristics and mechanical properties of lead-free solders. The vacuum melting process is a type of casting method used to fabricate Sn lead-free solder alloys where materials are melted under the protection of vacuum or other gases (hydrogen, argon, etc) in vacuum melting, which allows for precise control of the alloy composition and ensures a high degree of purity [31,32]. There is not enough study focused especially on the tensile properties of Sn-Zn based solders under elevated temperatures and strain-rate conditions.…”

The impact of minor additions of nickel and ZrO2 nanoparticles to eutectic Sn-9wt%Zn (SZ) prepared by vacuum melting technique was investigated. The morphologies and microstructures were carried out using an optical microscope (OM) and field emission scanning electron microscope technique (FESEM) escorted by energy dispersive x-ray spectrometry (EDX). The phase structure of the specimens was confirmed by an X-ray diffractometer (XRD). The results obtained demonstrate that small Ni addition causes a major grain refinement of β-Sn, due to the formation of the fine intermetallic compounds Ni5Zn21 and Sn3Ni4Zn3 phases and refines the formation of α- Zn lamellar phase. The melting temperature of the recently discovered solder alloys was lower than that of the eutectic Sn-Zn solders (∆Tm ~ 28 ºC) as a result of the preparation technique and the incorporation of Ni and ZrO2 nanoparticles. The tensile test showed enhanced the mechanical properties of SZ solder as a result of the addition of third elements. The experimental results showed that of all the alloys under investigation, the SZN903 alloy had the greatest UTS and YS values. The enhanced strength of the SZ-ZrO2 alloy defended the results of σUTS and increased the stress exponent parameters, n, by ∼20%. All solders had an activation energy Q that measured between ∼35.62 kJ/mol to ∼58.12 kJ/mol which comparable to the pipe-diffusion mechanism.
