A method has been developed for fabricating long, cylindrical rubber-mill rolls of boron carbide for use with abrasive materials. The technique consisted of initially hot pressing the boron carbide (to 90% of the theoretical density) to short, hollow cylinders having a length-to-diameter ratio of about one. This initial hot-press operation was followed by a second hot press to join or bond, and further densify, the short sections into a final compact having a length-to-diameter ratio of three. Flexural-strength data show that the integrity of the bond is comparable to that of the base material.
