Abstract
Official abstract text for this publication.
An alloy includes a mixture of aluminum, tin and magnesium. An amount of the magnesium is between about 2.5% and 6.5% by weight of the mixture. The alloy is binder jet printed and liquid phase sintered.
First claim
Opening claim text (preview).
What is claimed is: 1 . An alloy for liquid phase sintering in binder jet printing, the alloy comprising: a mixture of: aluminum; tin; and magnesium, wherein an amount of magnesium is between about 2.5% to 6.5% by weight of the mixture. 2 . The alloy of claim 1 , wherein the magnesium, the aluminum and the tin are in the form of an alloy powder. 3 . The alloy of claim 1 , wherein the magnesium, the aluminum and the tin are mixed together to form a powder mixture. 4 . The alloy of claim 1 , wherein the magnesium, the aluminum and the tin are combined in any combination of alloy and elemental powders. 5 . The alloy of claim 1 , wherein the amount of magnesium is between about 2.5% to 4% by weight of the mixture. 6 . The alloy of claim 1 , wherein an amount of the tin is about 1% by weight of the mixture. 7 . The alloy of claim 1 , wherein full densification of the alloy is achieved for a liquid phase fraction greater than about 8%. 8 . The alloy of claim 7 , wherein the liquid phase fraction is between about 8% and 20%. 9 . The alloy of claim 1 , wherein the aluminum is an alloy of aluminum. 10 . A method to form an alloy for binder jet printing, the method comprising: mixing: aluminum; tin; and magnesium to form a mixture, wherein an amount of magnesium is between about 2.5% to 6.5% by weight of the mixture; selectively combining the mixture with a binder to form a shape; debinding the mixture; and liquid phase sintering the mixture with nitrogen. 11 . The method of claim 10 further comprising holding the mixture at about 500° C. between debinding and liquid phase sintering. 12 . The method of claim 10 , wherein the magnesium, the aluminum and the tin are in the form of an alloy powder. 13 . The method of claim 10 , wherein the magnesium, the aluminum and the tin are mixed together to form a powder mixture. 14 . The method of claim 10 , wherein the magnesium, the aluminum and the tin are combined in any combination of alloy and elemental powders. 15 . The method of claim 10 , wherein the amount of magnesium is between about 2.5% to 4% by weight of the mixture. 16 . The method of claim 10 , wherein an amount of the tin is about 1% by weight of the mixture. 17 . The method of claim 10 , wherein full densification of the alloy is achieved for a liquid phase fraction greater than about 8%. 18 . The method of claim 10 , wherein the aluminum powder is an alloy of aluminum. 19 . An alloy for liquid phase sintering in binder jet printing, the alloy comprising: a mixture of: aluminum; tin; and magnesium, wherein an amount of the tin is about 1% by weight of the mixture and an amount of the magnesium is between about 2.5% to 6.5% by weight of the mixture, and wherein the remainder of the mixture is aluminum. 20 . The alloy of claim 19 , wherein the magnesium, the aluminum and the tin are combined in any combination of alloy and elemental powders.
