| Abstract: | The present work deals with the analysis of data on preparation and investigation of boron with different content of 10B and 11B isotopes. It was established that influence of isotopes on the structure and physical-mechanical properties of boron varies with regard to the type and percentage of an applied isotope. Microhardness of the specimens was measured at room temperatures. Peculiarities of changes observed in the values of microhardness, thermal expansion coefficients and characteristics of the relaxation processes are discussed from the point of view of probable changes in inter-atomic forces created due to substitution of natural boron atoms with their isotopes. |
