Viscosity and surface tension measurements on Fe-rich FeB liquid alloys

Measurements of viscosity and surface tension were made on Fe-rich FeB liqu id alloys for compositions: Fe85B15, Fe83B17, Fe80B20 and Fe75B25. Viscosit y of the liquid alloys was measured using the oscillating cup method. For s urface tension determinations we used the sessile drop method. The temperat ure range covered in these studies was 1473-1823 K. The observed deviation of the viscosity and surface tension from the ideal temperature and composi tion dependence, for the investigated liquid FeB alloys, indicates the effe ct of the B concentration on the short-range-ordered structures present in the liquid.
