PREPARATION AND FIBER FRACTURE OF METAL MATRIX COMPOSITE FEED-STOCK FOR POWDER INJECTION MOLDING.

n this study, the preparation of a range of metal matrix composite feedstocks and their characterization are presented. In order to achieve a uniform dispersion of metal powder and fibers in the binder, a co-rotating twin-screw extruder was used for feedstock preparation. Three formulations consisti...
