MMC DOWNHOLE TOOL REGION COMPRISING AN ALLOTROPIC MATERIAL

摘要

The disclosure provides rotary drill bits with bit head regions or other downhole tools with regions in which an allotropic material in a precursor region has been transformed from a first allotrope to a second allotrope in response to a trigger. The disclosure further provides methods of forming such downhole tools and methods of triggering an allotropic phase transformation during their use.
