Normal spectral emissivity, specific heat capacity, and thermal conductivity of type 316 austenitic stainless steel containing up to 10 mass% B 4 C in a liquid state

The normal spectral emissivity, specific heat capacity, and thermal conductivity of type 316 austenitic stainless steel (SS) containing B4C in the liquid state were experimentally measured over the composition range of SS -x mass% B4C (0 < x < 10) and wide temperature ranges using an electromagnetic levitator in a static magnetic field. The normal spectral emissivity and specific heat capacity were almost constant with temperature for all SS -B4C melts; thermal conductivities of the melts had a negligible or small positive temperature dependence. The B4C-content dependence of each property at 1800 K had a different tendency across the eutectic composition (approximately 3 mass % B4C) of the SS -B4C pseudo-binary system.

Automated summary

The normal spectral emissivity, specific heat capacity, and thermal conductivity of type 316 austenitic stainless steel (SS) containing B4C in the liquid state were experimentally measured. It was found that the normal spectral emissivity and specific heat capacity were almost constant with temperature, while the thermal conductivities had a negligible or small positive temperature dependence. The B4C-content dependence of each property had a different tendency across the eutectic composition of the SS-B4C pseudo-binary system.
