SYSTEM AND PROCESS FOR FRICTION CONSOLIDATION FABRICATION OF PERMANENT MAGNETS AND OTHER EXTRUSION AND NON-EXTRUSION STRUCTURES

摘要

A die tool and process are described that provide friction consolidation fabrication and friction consolidation extrusion fabrication products including permanent magnets, and other extrusion and non-extrusion structures. The present invention overcomes previous particle size, texture, homogeneity and density limitations in conventional metallurgy processes.

主权项

1. A friction consolidation process, the process comprising the steps of:
compressing a selected material under a selected compression load; and rotating the selected material in the compression direction at a selected rotation speed to apply a rotational shear force that frictionally consolidates grains of the material to a size below about 5 microns aligned along a selected crystallographic axis.
