A CUTTING INSERT OF A CERMET HAVING A CO-NI-FE-BINDER |
摘要 |
A cutting insert (2) including a flank face (6), a rake face (4), and a cutting edge (8) at the intersection of the flank and rake faces that is useful in the chip forming machining of workpiece materials is disclosed. The cutting insert comprises a cermet comprising at least one hard component and about 3 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. |
