The Analysis of Causes of the Damage of a Turbine Blade Made of Ti-6Al-4V Alloy

Abstract:

The main causes of the damage of a compressor’s turbine blade are documented and described in the article. The turbine blade was made from titanium alloy grade 5 (VT6, Ti-6Al-4V). The analysed segments of the turbine blade were damaged by corrosion and erosion. The sample from the damaged blade was compared with an undamaged reference sample. The observed substantial distinctions between microstructure of the damaged and the reference sample were found using of light and scanning electron microscopy. The observed distinctions of the microstructure were caused by the differences in the heat treatment process.
