MECHANICAL PROPERTIES OF HOT-PRESSED BERYLLIUM DEPENDING ON THE PROCESS PARAMETERS AND STRUCTURAL FACTORS
The influence of the structural factor (the content and state of impurities, the grain size, distribution of secondary phases, substructure, process parameters (temperature, pressure and process time)) on the level of the mechanical properties of a wide class of beryllium materials, received on various technologies of hot pressing is studied. It is established that the mechanical properties determined by the purity of the starting powder, grain size, the presence of cellular substructure, as well as the distribution of beryllium oxide and allocations of particles of secondary phases (fig. - 5, tables - 11, references - 5).
