Abstract:
This paper deals with the effect of Sn on the microstructure，physical properties，and welding per-formance of Zn-10Al -xSn Alloys by using OM，XRD diffraction , SEM and its EDS spectrum analyzer andSun10 universal testing machine. The results show that Sn can refine eutectoid structure and reduce the meltingtemperature of Zn-Al alloys. Spreading performance and the shear strength of welded joints are improved withthe adding of Sn element. The spreading area on copper plate is 122 mm’and the shear strength of weldedjoints is 53 MPa when the Sn element is added up to 12 wt. %e . Increasing the adding amount of Sn element,the spreading area and shear strength decrease. This is because intermetallic compound on interfacial growsrapidly.
