Expert Solution
Step 1: Introduction

   Thermal shock resistance refers to a material's capacity to withstand quick and abrupt temperature fluctuations.

  A temperature or thermal gradient, which generates random expansions at various sites inside the material, is a frequent scenario that creates a thermal shock in a material. This causes regions of stress and strain to act on the material at several sites during operation, making it brittle and possibly dangerous.
