Abstract

The article presents the mechanical properties of blades forgings from VT6 alloy, manufactured using three methods – a bulk stamping followed by single-stage annealing; a combination of a high-temperature annealing stage with heating for calibration and subsequent aging, as well as the high-temperature thermomechanical treatment method, which consists of heating for stamping, stamping calibration followed by quenching in water and aging. Particular attention in the article is paid to the characteristics of plasticity and impact toughness, as well as fatigue strength, taking into account the current issues of ensuring the reliability of the material of the first stages of compressor blades of aircraft engines.
