Gerasimov V.V., Visik E.M., Kolyadov E.V. The influence of the drift of the crystallization front on the structure of single crystal alloy castings ZHS32U obtained at the VIP NK
The article gives an explanation of the observed phenomenon development of the axes of thedendrites of the second order in the middle of the height of the cylindrical ingot diameter of 16 and a height of 200 mm. Development axes of the dendrites of the second order due to the drift of the solidification front in the direction of coolant (molten aluminum) on bo'l `shimi value than the maximum of its value for the particular alloy and casting machine. A scheme of the one-dimensional temperature field of casting with its division into four zones of differing aggregate state of the alloy and heat transfer conditions on the lateral surface of the sample. It is shown that the adjustment of the temperature and velocity parameters can be cast with a uniform interdendritic spacing over the entire height. Key words: superalloys, directionally solidified, the calculation of temperature and velocity parameters.

Results of model estimation of influence of maintenance for components of initial powdercharge of carbon-aluminium composites on their basic tribotechnical characteristics of composite materials for the wide range of composite compositions. It is shown that for carbon-aluminium composites, not containing the refractory including of Al2O3 and TiC, with the increase of maintenance of graphite from 15 to 45% the coefficient of friction goes down and are within the limits of 0,11…0,17. Introduction in the composition of material refractory particles of alumina or titan carbide and increase of their maintenance in a charge results to the substantial increase of coefficients of friction to 0,25…0,49 and wearproofness of materials as compared with carbon-aluminium composites, not containing ceramic particles. Key words:Carbon-aluminum composites, tribotechnical properties, elasticity modulus, modeling.

In this article it is pointed, what under uniform pressing of metallic porous body, when volume of pores, contained in this body, are decreasing, ratio of pores volume decrease, expressed in percentage, to body volume decrease, expressed in percentage, is equal to "coefficient of accordance between body volume and pores volume K", which is constant for the body. Coefficient K, in one? s turn, is equal to ratio of initial body volume, expressed in SI units, to initial pores volume, expressed in SI units also. Key words: metallic body, pores, volume, relative change, ratio, coefficient.

Isagulov A.Z., Kvon S.S., Kulikov V.Y., Filippova T.S., Sidorina Y.A. Investigation into the Properties of Titanium Carbide Based Materials Designed to Working at High Temperature
Investigated were the properties of titanium carbide based cermets containing 25…65% Ni-Cr or Ni-Co-Cr binder. Manufacturing regime and physical properties of those materials at room and elevated temperatures are given. Such mechanical properties as bending strength, tensile strength, impact toughness were measured. Usability of cermets as high-temperature materials was considered. Strength rupture was evaluated as a high-temperature strength indicator. Strength rupture decreases with an increase in binder content, just like normal rupture strength at high temperatures. It was found that in the investigated temperature range the material's properties are a function of binder content. Key words: cermets, titanium carbides, Ni-Cr binder, Ni-Co-Cr binder, physical and mechanical properties, high-temperature strength, impact toughness, sintering.
