Abstract

This study aims to develop a lead-free high-temperature solder alloy using Zn and Fe, investigating how varying Fe content impacts microstructure, melting behaviour, and properties. Alloys of Zn-xFe (x = 0, 0.005, 0.01) were fabricated via melting and casting. Increasing Fe content reduced hardness and electrical conductivity, with significant microstructural changes observed. Compared to a Zn-xMo study, our results outperformed in mechanical characteristics. Zn-0.01 Fe emerged as the optimal composition, exhibiting the highest melting temperature (425.81°C), ultimate tensile strength (41.88 MPa), while displaying lower hardness and conductivity. Its microstructure boasted smaller grain boundaries, contributing to superior mechanical properties.
