Effect of static tensile stresses on the damping capacity of porous titanium

The results of investigation of the damping capacity (DC) of porous titanium subjected to dynamic tangential stresses with the application of a static tensile stress are presented. It is shown that the DC of porous titanium depends on the size of the titanium-powder fraction and the residual porosity. It is established that static tensile stresses lead to a decrease in the logarithmic decrement in the majority of cases.Translated from Problemy Prochnosti, No. 7, pp. 98–101, July, 1990.     

Blast-furnace smelting with improved coke at OAO Zaporozhkoks

As an experiment, coke from batteries 5 and 6 at OAO Zaporozhkoks is used in blast furnace 5 at Zaporozhstal, in order to determine the influence of coke quality on blast-furnace operation. This research is associated with the prospects for coal-dust injection into the blast furnace at OAO Zaporozhstal.     

Neutron-physical calculations and experiments on a reactor in the first nuclear power plant built in the world

Methods for performing neutron-physical calculations of a reactor and the experiments performed during physical startup and subsequent operation are described. Starting with the simplest one-dimensional calculations during the reactor design process, the operation of the reactor is completed with three-dimensional calculations taking account of the heterogeneous structure of the core.Among the experiments investigations of the effect of water entering the graphite masonry during an accident with the fuel assemblies on the reactivity should be singled out.The method of partial fuel reloading, making it possible to decrease fuel-assembly burnout, has been implemented for the first time for the AM reactor.__________Translated from Atomnaya Énergiya, Vol. 98, No. 1, pp. 13–18, January, 2005.     

Theory of the positive column of a nonsteady electric arc in a channel containing a gas stream

The problem of a nonsteady arc column in a channel containing a gas stream is solved for an arbitrary law of variation of the current with allowance for the variability of the gas density, flow velocity, and flow rate.Translated from Inzhenerno-Fizicheskii Zhurnal, Vol. 42, No. 4, pp. 648–652, April, 1982.
