WAVE DISTURBANCE OF THE TEMPERATURE FIELD
IN LOW-THERMAL-CONDUCTIVITY MATERIALS

It has been established that under conditions where the 
heat flux supplied exceeds the level permissible for heating a material 
without the destruction of its surface, the velocity of propagation 
of heat is independent of the prehistory of heating and is determined 
by the steady-state value of the temperature on the surface being 
destroyed. The possibility of disturbing the temperature field in 
a wave manner has been shown; the wave disturbance is attenuated with 
increase in the heating time, if there is no removal of mass, and 
reduces the time in which the stationary regime of destruction of 
the surface in mass removal is reached. An analytical expression for 
calculation of the wave disturbance of the temperature field has been 
proposed.
