OPTIMAA / OPTImization of Microstructures and Mechanical Properties of Metallic Alloys Obtained by Additive Manufacturing – OPTIMAA

The range of metal materials offered for additive manufacturing (AM) remains limited while there is a real expectation of new materials for lighter metal devices or metal matrix composites with new or improved properties, particularly in related sectors such as the automotive, nuclear, aeronautical, and medical industries. The work planned as part of the OPTIMAA proposal will not only provide new material solutions (powders and bulk materials and prototypes) but also improve the degree of maturity (TRL) of these solutions to resolve the following issues: in the medical field, we will offer a new material (ZTM14N) to replace pure titanium and TA6V (stiffer than bone, presence of toxic elements…). In the aeronautical field, a composite material solution based on TA6V and zirconium oxide is used to replace TA6V (low fatigue resistance). A replacement material solution for zirconium (ZTP20Z) will also be implemented in the aerospace sector. To do this, the triptych “AM process—microstructure—properties (and performance) will be at the center of the work of LabCom OPTIMAA.
