Graded direct energy deposition in advanced alloys

Purpose and goal

** Denna text är maskinöversatt ** The project aimed to test the LMD (laser metal deposition) method with two different building materials. The goal of two different materials was to be able to build components with graded properties in three dimensions. These would then have better properties and be lighter than the corresponding conventional components

Expected results and effects

** Denna text är maskinöversatt ** The composite resulting from the project was found to have weldability and mechanical properties that were better or in par with conventional components.

Planned approach and implementation

** Denna text är maskinöversatt ** The method described in the proposal proved difficult to implement with the hardware available within the project time. An alternative arrangement which gave the same properties of the additively manufactured component was used instead. Thus, a new method was also needed to evaluate the mechanical properties and one was developed. Both the 3D construction method and the mechanical test method proved to be successful. In addition to the general increase in skills in the field, the industrial partners also received valuable data on their materials.
