WebAbstract. An electromagnetic levitation technique performed in a static magnetic field was used to measure density, surface tension, normal spectral emissivity, heat capacity, and thermal conductivity of molten 316L stainless steel (SS316L) and SS316L that contained 5 mass % B 4 C. The addition of 5 mass % B 4 C to the SS316L yielded reductions of 111 … Web*When range of values for temperature and emissivity are given, end ...
