Abstract

The effect of different regimes of recovery thermal treatment (RTT) on short and long-term mechanical properties and structure of the cast-casing elements that have exhausted their rated lifetimes are analyzed. A comparison of different RTT regimes is made, and the advantages and shortcomings of each regime are revealed. RTT parameters that provide optimal properties of the metal being treated are determined.
