Abstract

Abstract:

Effects on microstructure, molten temperature and corrosion of Sn-9Zn solder alloy was researched under magnetic field of 0.5 T by means of XRD,SEM and metal corrosion detecter etc. The results show that magnetic field can refine microstructure of Sn-9Zn solder alloy, molten temperature decrease by 2 ℃ and corrosion improve as well. It can be concluded that the magnetic field can promote Sn-9Zn solder to crystalize at special plane and restrict formation of rich-Zn phase,which refine microstructure of Sn-9Zn solder and improve its property.
