Contact fatigue in low-cycle loading of Wc-Co hard alloys for metal working

Fal'kovskii, V.A.; Kuralina, M.V.; Travushkin, G.G. (Проблемы прочности, 1985)

The proposed experimental method of examining the resistance to low-cycle fatigue makes it possible to approximate the laboratory conditions to the real loading conditions and predict the behavior of the alloy in service,
Temperature dependence of cracking resistance of 15KhSND steel and special features of its fracture. Report 2

Gol'dshtein, R.V.; Ovsyannikov, B.M.; Surovova, V.N. (Проблемы прочности, 1985)

In the previous article, we presented the results of investigations into the temperature dependence of the cracking resistance of 15KhSND steel in the temperature range --80° to +20° obtained using the methods which make ...
Rules of fracture development in the creep of heat-resistant steels

Berezina, T.G. (Проблемы прочности, 1985)

This work is an investigation of the basic rules of the origin and development of discontinuities in heat-resistant steels under cree conditions. The materials of the investigation were steam-line pipe and specimens of ...
Resistance to deformation and fracture of 35Kh3NM steel under conditions of shock loading

Gluzman, V.D.; Kanel', G.I.; Loskutov, V.F.; Fortov, V.E. (Проблемы прочности, 1985)

Investigations of the strength properties of materials under conditions of shock-wave loading have been stimulated by the necessity of prediction of the action of intense pulsed loads on various structures. Measurements ...
Change in the ductility characteristics of austenitic steels during deformation at different rates

Shinkarenko, E.T. (Проблемы прочности, 1985)

The present study investigates the ductility of stable austenitic steels 07KhI3AGI9N5 and 12KhI8N22T and metastable austenitic steel 03KhI3AGI9.
Deformation of metals at strain rates above 10⁴ sec⁻¹

Stepanov, G.V.; Kharchenko, V.V. (Проблемы прочности, 1985)

The deformation and fracture of structures under impulsive loading of a shock or explosive nature is predicted on the basis of equations of state of the material which are applicable within a broad range of strain rates. ...
Influence of technological parameters on the mechanical properties of NT-50 superconducting multistrand conductors at low temperatures

Lototskaya, V.A.; Il'ichev, V.Ya.; Buryak, V.P.; Matrosov, N.I. (Проблемы прочности, 1985)

The purpose of this article is to study the influence of thermomechanical working, strand diameter, and space factor on the mechanical characteristics of NT-50 alloy-base superconducting multistrand conductors in the ...
Surface strain-hardening of the blades of gas-turbine engines in an ultrasonic field

Yatsenko, V.K.; Stebel'kov, I.A.; Pritchenko, V.F. (Проблемы прочности, 1985)

The completed tests convincingly show that the time of strain-hardening of small blades of alloy VT8 by 1.3-mm-diam. balls should be no greater than 5 min if the edges are not protected by shields. Such strain-hardening ...
Effect of decarbonization of metal on the load-carrying capacity of cylindrical pressure vessels

Shirshov, V.P. (Проблемы прочности, 1985)
Effect of the peak temperatures and of the cooling rate on the damping properties of manganese-copper base alloys

Chaikovskii, B.S.; Yaroslavskii, G.Ya.; Bocharova, L.A. (Проблемы прочности, 1985)

We investigated alloys differing in chemical composition as well as by the regimes of heat treatment in the initial state (before heat cycling). Heat cycling consisted in heating blanks of a copper-manganese alloy to ...
