文摘

The plastic deformation of the ferrite workpiece is primarily due to dislocations. The dislocation length varies significantly with the tool microstructure. The friction coefficient decreases with increasing the carbide content in the tool. The wear of workpiece material is greatly influenced by the tool microstructure.
