The objective of this activity is to develop new titanium alloys which can take full advantage of the AM process to deliver products with high end structural performance. This will be performed with the following tasks:Identification of possible structures within spacecraft and launchers applications which can take advantage of the AM process. This will include the definition of target properties.Comprehensive literature review targeting the field of Rapid Solidification of titanium alloys, particularly focusing on inert gas atomization of powders.Microstructural modelling to develop relationships between the AM process and the microstructure of advanced titanium alloys. This will be performed using the CALPHAD approach.Manufacturing of samples to test target compositions without the need to make powder or wire.Manufacturing and testing of demonstrator parts for comparison with parts manufactured from conventional non-optimised powders.
