Structurally-phase transformations into difficultly processable materials as a wayofincrease ofwearresistance ofthe

In this work with attraction of a transmission and scanning electronic microscopy the experimental result of change geometry, structure and microhardness of chip from alloys VT23, AMc, HVG in an interval of speeds of cutting treatment 2-6000 m / min are adduced. The laws of interplay of dynamic plastic deformation and destructions on macro-, mezo- and mikro- levels are established.
