“…On fig. 1(a-c) treatment blank, cutter and formed chip with marked places of localization plastic deformation (εloc) are represented [22,23]. At treatment of aluminum alloy AMc (Vcut = 8 … 230 m/mines) traces of localization of plastic deformation did not observe, thus the chip "overflow" was formed, fig.…”

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 tool.

The structure and properties of discs from cast coarse-grained D16 alloy have been investigated with the help of optical metallography and transmission electron microscopy, after the traditional heat treatment (HT) modes or subjected to high pressure torsion (HPT) under pressure in 6 GPa at room temperature. Standard HT modes included: Т4 (hardening 495°С + natural aging at room temperature for 5 days) and Т6 (hardening 495°С + artificial aging at 185°С for 10 hours). It is shown that after HT of alloy D16 according to modes T6 and Т4, the sizes of the structural elements, compared with the original, decreased by about 4,8 times and the microhardness increased by 1,6 times. It is shown that after one or ten rotates of HPT in D16 alloy the sizes of structural elements, in comparison with initial, decreased by 393 and 899 times, and microhardness increased by 2,4 and 2,9 times, respectively. Detection of hardening hard, brittle and high-alloy copper γ2- phases (Cu9Al4) indicates the passage in the HPT process of the decomposition of a supersaturated solid solution (dynamic aging) in the planes of a local shift.

The article substantiates consistent patterns of wear at the example of microcutting materials in sliding bearings in dependence to grain sizes of abrasive cloths and hardness of bearing layers received with the use of vibroacoustic diagnostics and the method of artificial bases (MAB) in testing on the SMC-2 frictional machine. These patterns can be helpful for the assessment of quality and selection of materials for products [1,2], selection of the friction model [3], and selection of abrasive cloths for the diagnostics of the latter and assessment of the running-in period for the top coating.
