Purpose and goal
The project aims for a PhD thesis exploring the new superalloy ATI 273TM, designed for high temperature components with a focus on aerospace applications. Within project BEYOND, laboratory investigation of ATI 273TM is being considered at TRL level 2. The knowledge and understanding from the study will help GKN reach TRL level 3, for a material which can potentially be used in LPT and TEC.
Expected effects and result
GKN can benefit from introducing the new alloy ATI 273TM in high temperature components. Expected results include improved jet engine efficiency, reduced fuel consumption and lower emissions. ATI 273TM contains less cobalt than Waspaloy, which reduces the environmental impact. The project aims to create TTT and CCT diagrams, increase knowledge about heat treatment, microstructural development, mechanical properties and high temperature stability, and result in licentiate and doctoral thesis.
Planned approach and implementation
An integrated methodology with advanced scientific methods will study ATI 273TM, focusing on: Thermodynamic characterization Optimization of heat treatment processes Advanced material characterization Mechanical testing Thermomechanical properties Weldability Milestones: MS1: Literature overview presentation at LTU and GKN MS2: Licentiate thesis MS3: Doctoral thesis
