Consideration has been given to the pulse action of a hot gas flow on a wall of chromium‐nickel steel; an analysis has been made of the processes and phenomena of mechanical and thermoerosive wear and fatigue failure of the wall. A structural model of thermal fatigue of chromium‐nickel steel has been developed. The wear of the wall of a tube with an inside diameter of 0.03 m under the pulse action of the gas flow and thermal stresses of the second kind has been evaluated numerically. The results of short‐duration mechanical tests of 12Kh18N10T steel after thermocycling have been given. [ABSTRACT FROM AUTHOR] |
