СВЯЗЬ МЕЖДУ МИКРОТВЕРДОСТЬЮ СПЛАВОВ Ni–Cr–Mo И ЭНЕРГИЕЙ ВНЕДРЕНИЯ ИНДЕНТОРА В ВЕЩЕСТВО

The dependence of the microhardness HV of ternary solid solutions of Ni–Cr–Mo based on the composition of the nickel is investigated. The formula relating the microhardness HV with the amount of its constituent components, expressed in at. %, is suggested. The linear dependence between microhardness of samples and concentration of impurities is set in the 0–22 at. % Chromium and 0–16 atm. % Molybdenum. It is shown that the using the energy of indenter’s implementation into the sample allows us to estimate not only the strength of the crystal lattice of the substance, but also to link it with the energy of the crystal lattice. Along with microhardness introduced the quantity, called the work we do destruction, allowing to estimate the energy gap of the interatomic bonds in the implementation of the indenter into the alloy. Along with microhardness we introduced the quantity, that was called the work of destruction, allowing to estimate the energy of the gap of the interatomic bonds when implementing of the indenter into the alloy. It is shown that introduction of chromium and molybdenum has a greater effect on the value of microhardness, than the interaction between these components.
