Thermal Stress Fracture of Brittle Ceramics by Conductive Heat Transfer in a Liquid Metal Quenching Medium

Abstract

Observed and calculated values of the critical quenching temperature difference for circular rod specimens of a soda‐lime‐silica glass and polycrystalline alumina quenched in a liquid Pb‐Sn alloy indicate that thermal stress fracture was caused by conductive heat transfer, in support of the original theory of Hencke, Thomas, and Hasselman.
