Накратко на български

Механизмите на пукане при умора на алуминидни интерметали се анализират чрез наномащабно картографиране на деформациите. Разбирането на тези процеси помага за създаване на по-издръжливи леки материали за авиацията, което може да намали разхода на гориво и вредните емисии.

High Cycle Fatigue Cracking of Meso- and Micromechanical Testpieces of Aluminide Intermetallics, with in situ Nanoscale Strain Mapping

The aim of FracTAlS is to increase the understanding of the deformation mechanisms leading to and mediating cracking in high cycle fatigue loading, particularly in lightweight, structural aluminide intermetallics, in order to better direct microstructural and alloy development. Such materials are highly desirable for many rotating and airborne engineering applications but often suffer from prohibitive brittleness, particularly in fatigue. The project applies a combination of nanoscale strain mapping techniques on in-situ meso- and micro-mechanical testing, to study deformation behaviour. Currently, the European hub plays a central role in the research and development of advanced gamma titanium aluminide alloys, such as for improved processability, and the large-scale production of γ-TiAl components. However, no significant improvements have been made to the fatigue properties of the lightweight γ-TiAl alloys in the past few decades, effectively limiting their widespread application in higher volume industries where they could result in considerable increases in fuel efficiency. This project is closely aligned with EU policy on climate action and sustainable development: it targets reduced emissions through reduced hydrocarbon fuel consumption; its success will serve to increase the European confidence and knowledge-base in these material systems and, through further interaction with European industry, the extent of their use.

Цел на проекта

The aim of FracTAlS is to increase the understanding of the deformation mechanisms leading to and mediating cracking in high cycle fatigue loading of lightweight, structural aluminide intermetallics, in order to better direct microstructural and alloy development. Such materials are highly desirable for many rotating and airborne engineering applications but often suffer from prohibitive brittleness, particularly in fatigue. The project applies a combination of nanoscale strain mapping techniques recently developed by the host institution, and by Dr. Edwards, on novel in-situ meso- and micro-mechanical fatigue testing setups, to study deformation behaviour upon fatigue loading. Currently, the European hub plays a central role in the research and development of advanced gamma titanium aluminide alloys, such as for improved processability, and the large-scale production of γ-TiAl components. However, no significant improvements have been made to the fatigue properties of the lightweight γ-TiAl alloys in the past few decades, effectively limiting their widespread application in higher volume industries where they could result in considerable increases in fuel efficiency. Similarly, Mg aluminides, such as the γ-Mg17Al12 phase, possess outstanding strength to weight properties; given sufficient improvements to their toughness and fatigue performance, they would be excellent candidates for structural components in future, more ecologically friendly, aero-propulsion technologies where the operational temperatures are lower than gas turbine engines (e.g. electric and hybrid-electric). This project is closely aligned with EU policy on climate action and sustainable development as it targets reduced emissions through reduced hydrocarbon fuel consumption; its success will serve to increase the European confidence and knowledge-base in these material systems and, through further interaction with European industry, the extent of their use.
