1. It is shown that the most reliable values of the parameters σ0 and Ky in the equation of grain boundary strengthening can be obtained from the dependency of the true limit of elasticity σe on the grain size D−1/2. 2. The concept of the normali

1. Dispersed zirconium nitrides in amounts up to 4 vol. % lead to substantial strengthening of niobium without notably reducing the low-temperature ductility. The strength-to-weight ratio of the alloys is at the same level as that of the best niobium

1. It is shown that different values of compressive and tensile yield stresses (the SD effect) are exhibited not only by dispersion-hardened alloys with oxides but also by various refractory metal alloys strengthened with carbides and nitrides, the m

1. We studied the temperature dependence of the mechanical properties and fracture surface relief of a dispersion-hardened vanadium alloy with a strong interface within the temperature range −196 to 1500°C. 2. It was shown that the dispersed nitri
