Pick-style tool with a cermet insert having a Co-Ni-Fe-binder |
摘要 |
A pick-style tool that includes an elongate tool body with an axially forward end and an axially rearward end, and a hard insert affixed to the tool body at the axially forward end is disclosed. The hard insert comprises a WC-cermet comprising tungsten carbide and about 5 wt. % to 27 wt. % Co-Ni-Fe-binder. The Co-Ni-Fe-binder is unique in that even when subjected to plastic deformation, the binder substantially maintains its face centered cubic (fcc) crystal structure and avoids stress and/or strain induced transformations.
