 Project objective

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.

Are you the coordinator (or a participant) of this project? Plaese send me more information about the "TIALCRACKS" project.

For instance: the website url (it has not provided by EU-opendata yet), the logo, a more detailed description of the project (in plain text as a rtf file or a word file), some pictures (as picture files, not embedded into any word file), twitter account, linkedin page, etc.

Send me an  email (fabio@fabiodisconzi.com) and I put them in your project's page as son as possible.

Thanks. And then put a link of this page into your project's website.

The information about "TIALCRACKS" are provided by the European Opendata Portal: CORDIS opendata.
