Novel Ni-based materials for additive manufacturing of the components for high-temperature applications
|Coordinator||CHALMERS TEKNISKA HÖGSKOLA AKTIEBOLAG - Institutionen för material- och tillverkningsteknik|
|Funding from Vinnova||SEK 2 000 000|
|Project duration||August 2016 - September 2018|
Purpose and goal
The main target of the project was to develop generic model allowing to establish methodology for rapid development of the Ni-base alloys with tailored properties for specific applications, produced by LPBF. Characteristics of the powders for AM for alloys of interest, thermodynamic simulation platform, method for powder manufacturing and robust LPBF process parameters were established, allowing to produce fully dense defect-free components. Validity of the developed concept was tested on physical demonstrator manufactured and successfully tested in the project.
Expected results and effects
The project allowed to create knowledge base regarding critical factors of alloy design, powder characteristics and AM fabrication recipes for successful manufacturing of precipitation-hardened Ni-based alloys. This allowed to create a generic platform for rapid development of powder grades for AM and increase capacity to process difficult-to-build materials. Established method for rapid materials development for AM can be easily transferred to other AM application as automotive, medical, etc.
Planned approach and implementation
Establishment of the required powder characteristic and manufacturing process for the powder and LPBF fabrication recipes for difficult-to-build Ni-base alloys will allow Höganäs to further develop and introduce this powder on the market for AM in near future. Presence of the novel material for AM for high-temperature applications will allow Siemens IT to increase number of components produced by AM and significantly increase its components portfolio for repair with long-term economic benefit.
