Elongate rotary tool comprising a cermet having a Co-Ni-Fe binder |
摘要 |
An elongate rotary tool including at least one cutting edge that is useful in the machining of workpiece materials is disclosed. The elongate rotary tool comprises a cermet comprising at least one hard component and about 0.2 wt. % to 19 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.
