Crack growth threshold analysis in TiAl alloys

Obiettivo

The objective of the project is to investigate the fatigue crack growth (FCG) threshold and rate for long as well as short cracks of second generation TiAl alloys suitable for use in the Intermediate Pressure Turbine (IPT) of the UltraFanTM engine.

The work includes in detail all investigations specified in the Call for Proposals JTI-CS2-2014-CFP01-ENG-03-04, that are:

• determination of the FCG threshold and rates at load ratios R of 0.1 0.5 0.8 at room temperature and at 750 °C,

• determination of the variation of these material properties at room temperature for three different heat treatments (centre and extremes of the heat treatment window) at load ratios R of 0.1 0.5 0.8 and

• determination of the effect of defect type (defects from manufacturing, handling and foreign object damage (FOD)), morphology and size on the fatigue properties at room temperature and at 750 °C at load ratios R of 0.1 0.5 0.8.
