ENHANCEMENT OF THE DURABILITY OF AMG6M ALLOY BY ENERGY TREATMENT UNDER THE CONDITIONS OF CREEP

摘要

Under the conditions of creep, we study the influence of intermediate energy treatment of the specimens of AMg6M alloy on the mechanical characteristics and microstructure of the material. It is shown that the combined energy treatment, including the action of tensile and compressive stresses in the thermal field with subsequent impact ultrasonic treatment, increases the time to failure of AMg6M alloy and its characteristics of short-time strength. It is shown that the improvement of the strength characteristics is obtained due to the healing of defects and an increase in the density of dislocations.
