摘要：

During stress rupture testing and also during operation of components of high-strength alloy ZhS6U there is a change in structure and phase composition and an increase in dislocation density; gamma prime -phase particles coalesce and secondary dispersed precipitates of it form. Structural and phase changes are overcome partly or completely by restoration vacuum heat treatment. On achieving a critical dislocation density microcracks may generate along grain boundaries. As a result, restoration of opertaing capacity becomes impossible.
