Abstract

The operational characteristics regarding the foundry process can definitely affect the final microstructure. Such characteristics of the process can be translated by the solidification thermal variables such as cooling rate and growth rate. The use of lead (Pb) is a drawback in the modern soldering industry, which is justified based on the high toxicity of lead. As a consequence, several alternative alloys are being proposed so that they could replace Sb-Pb based alloys. Binary and ternary Sn-Ni, Zn-Sn-Cu and Sn-Bi-Sb solder alloys seem to be promising materials to be examined. Chemistry variation and microstructures of these alloys are some aspects to be elucidated. In the case of ternary Al-Si-Cu, the effects of cooling rate on the morphology and distribution of the formed phases are still tasks to be accomplished. Thus, this project aims to characterize in details the microstructure evolutions of the mentioned metallic alloys directionally solidified under transient conditions. The wetting behavior is considered as an essential attribute for commercial solder alloys. Thus, the Zn and Sn based alloys will be characterized by contact angle determination. Functional relationships will be established regarding microstructure-thermal parameters-mechanical resistance. (AU)
