Abstract

The article addresses the problem of assessing the expected content of non-metallic inclusions and other defects in materials used for manufacturing rotary components of turbines and compressors for aircraft gas turbine engines. The importance of objective information on defects not detected by non-destructive testing methods for the reliable determination of the safe service life of the engine is highlighted. Various methods for collecting and processing information on the quantity and size of defects in the material are reviewed, with their advantages and disadvantages listed. The choice of research directions aimed at developing a methodology for quantitative assessment of defects in granulated alloys is reasoned.
