Re-Melting Nb–Si-Based Ultrahigh-Temperature Alloys in Ceramic Mold Shells
In furnaces with different heating elements, Nb−Si based ultrahigh-temperature alloy rods were re-melted in pure yttria mold shells and zirconia face-coat mold shells at 1850 °C for 30 min. The results evidenced that in the furnace with a tungsten heating element, the microstructu...
