Sažetak
Experimental data on the short-term strength and plasticity of niobium alloy 5VMTs of the system Nb-W-Mo-Zr in its initial state, after annealing, and with a silicide-ceramic protective coating obtained by testing in vacuum, an inert atmosphere, and in air in the temperature range from 290 to 2270 K are analyzed. The process of microcrack initiation and propagation in the protective coating and matrix is investigated in high-temperature static tension. The limiting plastic strain values have been established at which the composite retains its load-carrying capacity in high-temperature aggressive and oxidizing gas atmospheres.
