Science To Production


Acoustic-emission investigations of the effect of the rate of cooling the materials of petroleum hydrocracking reactor heated in a hydrogen atmosphere are carried out. It is established that crack formation and lamination processes are slowed down with a decrease in the cooling rate of the specimens.
