The thermophysical properties of N36 type Zr-Sn-Nb-Fe alloy were studied within a temperature range of 1750-2250 K. The addition of alloying elements led to an increase in specific heat, surface tension, and viscosity. Both surface tension and viscosity displayed larger changes with temperature compared to Zr.
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.
