Method for forming hollow profile non-circular extrusions using shear assisted processing and extrusion (ShAPE)

A shear assisted extrusion process for producing high entropy alloys;

• the process comprising the steps of:
• positioning preselected high entropy pre-cursor materials in contact with a rotating scroll pattern on a face of a rotating die within a shear assisted extrusion device, the scroll pattern including grooves configured to draw material into an aperture of the die;
• and
• simultaneously applying a rotational force and an axial force upon the pre-cursor materials by rotating the scroll face and pushing the scroll face into the pre-cursor materials sufficient to cause plasticization and mixing of the pre-cursor materials at an interface of the rotating scroll pattern with the pre-cursor materials thereby homogenizing and consolidating the pre-cursor materials into a high entropy alloy that is extruded through the aperture of the rotating die.
