Abstract

Complex research of the reasons of operational destruction of boards of generators from AL9 and VAL8 aluminum alloys is conducted. Methods of optical and electron microscopy, x-ray microanalysis and chemical analysis is evaluated microstructure, chemical composition and nature of destruction of details is studied. It is established that destruction of details has occurred at action of single static load (hydraulic shock). Destruction was promoted by lack of radius of transition in place of change of thickness and the raised level of porosity in generator board from AL9 alloy.
