Under high-temperature and short-load conditions, the plasticity of metal materials increases； However, after metal materials are cooled under high-temperature and prolonged loading conditions, their plasticity decreases significantly, their sensitivity to notches increases, and they tend to exhibit brittle fracture. This property of metal materials is known as thermal fragility.

Thermal brittleness: When metal materials are subjected to high temperatures and short-duration loads, their plasticity increases. However, after cooling following exposure to high temperatures and long-duration loads, their plasticity decreases significantly, their sensitivity to notches increases, and they tend to suffer from brittle fracture.
