The reason for the sawtooth chips is that the adiabatic shear localization occurs in the primary deformation zones when thermalsoftening exceeds strain and strain rate hardening.
锯齿形切屑产生的原因是第一变形区内因热软化超过应变和应变率强化而发生了绝热剪切局部化。

Mechanism of damage of clay pot for utensil glass melting, such as softening deformation at high temperature, corrosion by molten glass, crack by thermal shock, etc was studied.
对熔化器皿玻璃等的粘土质坩埚使用中的高温软化变形、玻璃液侵蚀、热震开裂等损毁机制进行了分析研究。
