Abstract
Official abstract text for this publication.
Method for manufacturing an aluminium alloy part by additive manufacturing that includes a step in which a layer of a mixture of powders is locally melted then solidified, wherein the mixture of powders includes: first particles that include at least 80 wt. % aluminium and up to 20 wt. % one or more additional elements, and second particles of ZrSi 2 , the mixture of powders including 1.8 wt. % to 4 wt. % second particles.
First claim
Opening claim text (preview).
The invention claimed is: 1. Method for manufacturing an aluminium alloy part by additive manufacturing comprising a step in which a layer of a mixture of powders is locally melted then solidified, wherein the mixture of powders comprises: first particles comprising at least 80 wt. % aluminium and up to 20 wt. % one or more additional elements, and second particles of ZrSi 2 , the mixture of powders comprising 1.8 wt. % to 4 wt. % second particles, and wherein, during the additive manufacturing, ZrSi 2 decomposes to form in situ an Al 3 Zr germinating phase. 2. Method according to claim 1 , wherein the mixture of powders comprises 1.9 wt. % to 2.5 wt. % second particles. 3. Method according to claim 1 , wherein the second particles have a size ranging from 50 nm to 5000 nm. 4. Method according to claim 1 , wherein the second particles have a size ranging from 100 nm to 1000 nm. 5. Method according to claim 1 , wherein the second particles have a size ranging from 400 nm to 600 nm. 6. Method according to claim 1 , wherein the first particles have a size ranging from 10 μm to 120 μm. 7. Method according to claim 1 , wherein the first particles have a size ranging from 20 μm to 65 μm. 8. Method according to claim 1 , wherein the additional elements are selected from Cu, Si, Zn, Mg, Fe, Ti, Mn, Zr, Va, Ni, Pb, Bi and Cr. 9. Method according to claim 1 , wherein the aluminium alloy is alloy 7075, alloy 6061, alloy 2219 or alloy 2024. 10. Method according to claim 1 , wherein the manufacturing method is a selective laser melting process. 11. Method according to claim 1 , wherein the manufacturing method is a selective electron beam melting process. 12. Method according to claim 1 , wherein the mixture of powders is produced in a 3D dynamic mixer.
