摘要：
Foundry sand molds and cores are provided which incorporate glassy metal reinforcing filaments. Molds prepared from the sand composition of this invention provide greater strength before and during metal casting. As the casting solidifies, the temperature of the reinforcing filaments rises, the filaments devitrify and become weak and the mold can be crumbled for easy removal of the casting.
