Theoretical calculations of the surface tension of Ag_(1-x)-CU_(x) liquid alloys

摘要

The surface tension of silver-copper binary liquid alloys is calculated, in the frame work of Eyring theory. The calculations were made for different compositions (mole fraction, x_(Cu) = 0, 0.2, 0.4,0.6, 0.8 and 1), in the temperature range 1100-1800 K. The surface tension decreases with temperature increase, at a fixed copper fraction x_(Cu), and increases with increasing copper content. The calculated results are appropriately compared with existing literature data.
