Abstract
Embodiments of the invention relate to liquid metal embrittlement (“LME”)-resistant superabrasive compacts, methods of making the same, and drill bits incorporating the same. The LME-resistant superabrasive compacts include a braze-resistant region on one or more portions of a substrate expected to be under residual tensile stress and susceptible to LME during brazing.
