This thesis focuses on the experimental research of the viscosity and magnetic field of pure Ag, pure Sn and Ag-Sn alloys (Ag80.5 Sn19.5,Ag50.4Sn19.5 and Ag3.2Sn96.8(all in at.%)) Most examinations are executed with an oscillating vessel method and the facts of this approach are observed. The purity of the Tin and Silver and its alloys affects are the measured viscosity criterions and we consult a value of among 0.1–20 mPa s. for the pure component at the melting point. The relationship between viscosity and magnetic field strength discusses by using high-temperature melt viscosity measuring instrument with a horizontal magnetic field. The viscosity of multivariate components is discussed, and the preliminary research work on the track of the mathematical model for the viscosity of the multi-alloy melt is carried out. The experimental results show that the viscosity fit well with the Arrhenius formula under the magnetic field and the viscosity of all melts increases as the horizontal magnetic field intensity enhances.
On this basis, the connection among the viscosity and structure of liquid were discovered along with the attention. The effect of the external magnetic fields on the viscosity was reconnoitered too. The viscosities of Ag-Sn metal melts increase with decreasing temperature. As indicated by the magnetic field strength, significant increments of the viscosity were audited. A metallographic study is reported of the phases that occur in Ag–Sn alloys containing.
