Abstract
Using instrumental indentation, we studied the regularity of elastoplastic deformation of workpieces from alloys aluminum AMc, titanium VT23 and steels 45, HVG with FCC, HCP and BCC lattices, respectively. It was shown that with increasing indentation depth, instrumental hardness (H1T), elastic modulus (E1T), their ratios (HIT/EIT) tend to the values of classical microhardness Hµ, Young’s modulus E and their ratio (Hµ/E). The nature of localization of plastic deformation of alloys near the surface of the indenter is determined. The reason for the hard workability of titanium-based alloys is determined.
