Abstract

Hexagonal boron nitride (HBN) is converted to cubic boron nitride (CBN) within a transition metal alloy solvent system containing a small percentage of aluminum. Precipitous drops in the conversion of HBN to CBN occur as the ratio of the weight of HBN to the weight of metal in the initial mixture increases beyond some maximum yield ratio that may be routinely determined for each alloy. An abrasive body is produced in which the binder for the CBN grains is the metal alloy solvent itself, e.g., a superalloy.
