Temperature Dependence Of Thermophysical Properties For Liquid Zr-Sn-Nb-Fe Alloy Measured At Electrostatic Levitation State

The thermophysical properties of N36 type Zr-Sn-Nb-Fe alloy were investigated within the temperature range of 1750-2250 K. The liquid density at liquidus temperature and its temperature coefficient are determined as 6.28 g cm-3 and 2.78 & times; 10-4 g cm-3 K-1. The liquid thermal expansion coefficient at TL is 4.4 & times; 10- 5 K- 1. The liquid specific heat also displays a linear relationship versus temperature. The addition of alloying elements causes an apparent increase of specific heat, surface tension and viscosity. Moreover, both surface tension and viscosity display a larger change versus temperature in comparison with Zr.
