Formation of nanostructure and tool wear during cutting treatment of titanium alloy

This volume contains papers which were presented on the International Scientific Conference "New Materials and Technologies in Mechanical Engineering" (NMTME 2019, March 12 - 15, 2019, St. Petersburg, Russian Federation)Article Preview Abstract: Methods of the optical metallography, TEM, SEM-technique, tests for hardness and wear resistance are used to investigated the structural - phase transformation in metal blanks from alloy VT23 at cutting treatment in an interval of speeds 2...120 m/min are given. The patterns of interaction of dynamic plastic deformation and destructions on macro-, meso-, micro-and nanolevels are determined. It is shown that the formation in metal blank of modulated high-tensile secondary nanostructures promotes a heightening of a protective wearproofity of treated metal blank, but cutting edge, lowering a wearproofity, of the cutting toolVytauto Didžiojo universitetasŽemės ūkio akademij
