| dc.description.abstract | The act of soldering that is devoid of any debilitating health hazards is a global concern necessitating the development of varied lead-free solders exhibiting desirable solderability. In this study, a lead-free solder composed of tin-iron millscale-copper (Sn-FeO-0.2Cu) alloy was fabricated by casting and characterised for mechanical properties critical to its functionality. The used iron millscale (IMS) was varied from 1-5 wt.%. The cast alloy samples were evaluated for microstructure and mechanical properties (elastic modulus, yield strength, ultimate tensile strength and hardness) using optical microscope and relevant state of the arts mechanical characterisation tools respectively. Results showed that the mechanical properties of the fabricated solders compared favourably with standard solders. This could be attributed to the coherency of IMS with the tin matrix on one hand and the role of dislocation motion impediment played by the Fe-Cu intermetallic formed within the relatively soft tin matrix on the other. The solder melted in the range of 245-255 0C suggesting its suitability for soldering electric motors, car radiators and other high melting point (HMP) soldering. | en_US |
