Popis: | Results are given for determining the characteristics of short-term creep and stress-rupture strength of molybdenum-tungsten alloys with solid-solution and combined strengthening prepared by powder metallurgy at temperatures of 1500, 1750, and 2000°C. Empirical equations are obtained describing the dependence of creep rate and time to failure on applied stress. It is established that introduction into Mo-30% W alloy of finely dispersed niobium carbide and carbon particles markedly improves its high-temperature strength characteristics. |
