Abstract

Complex research of products from AMg4,5 aluminum alloys and AMn after long-term operation for the purpose of identification of signs of degradation of material is conducted. Mechanical tests for assessment of strength properties of base material and welded seams, are carried out by methods of non-destructive testing, optical and scanning microscopy the material structure is investigated, the fractographic analysis of the destroyed samples is carried out. It is established that degradation signs at observance of operating conditions do not come to light.
