The reason why the mechanical strength of graphite products increases with the increase of temperature can be explained as follows: 1. Graphite products do not produce local plastic deformation at low temperature, so even if a relatively low load is given, the stress concentration will cause the fracture.
However, when the temperature rises to a certain degree, due to the appearance of a plastic state, local deformation is generated near the stress concentration point, the stress is dispersed, even if a relatively large load is applied, will not cause the fracture.
2. Due to the linear expansion coefficient of graphite crystal is larger anisotropy, after being cooled from high temperature can produce larger stress within the grain, due to the external force superposition of internal stress value is bigger, the strength of the low temperature when the graphite is low, but when heated to a certain temperature gradually reduce internal stress, so the mechanical strength increases with temperature rise.
