Abstract
Due to the toxicity of Pb in the soldering alloys, new alloys (lead freeLead free ) are suggested by scholars especially for high-temperatureHigh temperature applicationsApplications . One of the alloys recommended so far is Bi–AgBi-Ag . This alloy has certain similar features to Pb–Sn alloys. Thus, the study focused on several candidate alloys (Bi–1.5–2.5–3.5 wt%Ag) as alternative soldersSolders . In this paper, the mechanical propertiesMechanical properties were studied using shear testShear test . It can be found from the shear testShear test results that increasing the amount of Ag content in the solderSolder matrix positively impact the maximum shear stress and shear strain. The highest maximum shear stress and strain were observed at Bi–3.5 wt%Ag with the value of 13.355 MPa and 44.136 MPa, respectively. Furthermore, the lowest maximum shear stress and strain were observed at Bi–1.5 wt%Ag with the value of 11.032 MPa and 24.955 MPa, respectively. Hence, the fracture behavior shifted from brittle to ductile.
