High Temperature – Small-Scale Sub-Surface Deformation assisted by Oxidation

Project description

Small deformations create big problems for structural parts

Large structural components in aeronautical engines and power plant applications withstand tremendous loads and severe temperatures day in day out. These obvious threats can create insidious and invisible microscopic subsurface deformations that eventually lead to the demise of such components, with serious consequences. Oxidation can accelerate subsurface deformation, which in turn increases surface reactivity, creating a dangerous cycle of destruction. The EU-funded HT-S4DefOx project is developing experimental techniques and simulations to better characterise the thermal, mechanical and chemical interactions that modulate the evolution of subsurface deformations. Enhanced knowledge of material behaviour should lead to improved designs and monitoring technologies as well as earlier interventions to extend the lifetime of critical structural components.
