Abstract: A consolidated material formed by powder metallurgy is provided. The consolidated material includes particles of a first component consolidated with particles of a second component. The first component is a transition metal selected from group 4, group 5, group 6, or group 7 of the periodic table of the elements, or an alloy thereof. The second component is a solid lubricant. Also provided is a method of making the consolidated material and articles made from the consolidated material.

Abstract: The present disclosure provides for a method of making a part using powder metallurgy and material extrusion. The method includes forming a mold of a first material using material extrusion. The method includes depositing a second material within the mold. The second material is deposited as a powder. The method includes compacting the second material within the mold, and heating the mold and the second material within the mold. During the heating, the mold is separated from the material by melting, evaporating, or burning of the first material, and the second material is sintered. Also provided for are parts made by the method and a system for making such parts. The system includes a material extrusion head and a powder deposition head. Each head is articulable along three axes.

Abstract: Alloys and processes for making and using same. In some examples, an alloy can include greater than 50 wt % to less than 65 wt % bismuth; greater than 35 wt % to less than 50 wt % tin; about 0.01 wt % to about 2.5 wt % indium; and at least one of: about 0.01 wt % to about 2.5 wt % antimony, about 0.01 wt % to about 0.5 wt % gallium, about 0.01 wt % to about 4 wt % zinc, and about 0.01 wt % to about 2.5 wt % chromium, with all weight percent values based on a total weight of the alloy. In other examples, an alloy can include greater than 50 wt % to less than 65 wt % bismuth; greater than 35 wt % to less than 50 wt % tin; about 0.01 wt % to about 2.5 wt % indium, and less than 1 wt % of lead, with all weight percent values based on a total weight of the alloy.
