Abstract:
1. A method of evaluating a volume of superabrasive material, the method comprising; exposing the superabrasive material to radiation, wherein the superabrasive material includes a plurality of diamond grains defining a plurality of interstitial spaces, and wherein the superabrasive material includes a first region and a second region, the first region having a catalyst material disposed in at least some of the plurality of interstitial spaces in the amount of about 1 weight percent to about 7.5 weight percent of the superabrasive material, and wherein the second region is a catalyst diminished region; monitoring a reaction of the radiation to which the superabrasive material is exposed, wherein monitoring the reaction includes monitoring at least one of the group consisting of backscattered radiation and x-ray radiation; and determining a location of the boundary between the first region and the second region of the superabrasive volume in response to the monitored reaction of the radiation, the location of the boundary being approximately 500 μm or greater from a working surface of the volume superabrasive material.
