The Superpore-X project aims to develop new materials and technologies for gas

turbine seals using functionally graded porous Hastelloy-X (H-X) alloys. The

project's vision is to improve the performance and lifetime of these materials

compared to existing honeycomb seals. The main hypothesis is that the hightemperature performance of the new porous sealing materials can be enhanced

through a powder-metallurgy-based fabrication approach. This approach offers

flexibility in controlling pore size and distribution, including the ability to create

porous functionally graded materials. Additionally, the proposed method utilizes

readily available, cost-effective, and environmentally friendly substances as

porosity forming agents (“space holders”). The primary scientific goal is to

establish a relationship between the fabrication process, structure, and properties

of porous H-X alloys by conducting experimental studies on the fundamental

phenomena governing the formation of the porous structure.
