This programme will investigate the fatigue crack growth threshold of second generation TiAl alloys suitable for use in the IP turbine of the UltraFan engine. The alloy will be defined by Rolls-Royce. This package of work will determine the fatigue crack growth threshold and crack growth rates, evaluate the effects of temperature and also the effects of the variation in properties within the designated heat treatment window. The influence of original defect size and morphology is also within scope.  Please refer for the full and formal topic description to Annex III of the Clean Sky 2 Work Plan 2014-2015 Amendment nr. 1  Version 3 (see under the tab "Topic Conditions and Documents")
