CONSTRUCTIONAL MATERIALS, PHYSICAL METALLURGY

Khorev A. I. — Fundamental and applied investigation of the composite materials based on titanium

Fundamental and applied research aimed at the advanced composite materials creation (KM) on the grounds of high-strength constructional titanium alloys for high temperature applications were carried out. KM intended for the manufacture of aircraft parts and assemblies. The problems of the complex alloying, thermal, thermomechanical processing and texture strengthening, composite materials creating were considered. "Pseudo" α-alloys BT18, BT38; α + β-alloys BT23, BT23M, BT43; β-alloys BT-19, BT19-1 and another were developed, recommended for use at the creation of the composite materials and structures. A composite material with an external reinforcement is developed, consisting of thermally hardened alloy capacity BT23 braided with plastic VNIVLON and showing high structural strength and specific strength. Created new titanium alloy BT43 and new reinforcing fibers will improve the specific strength of KM.
Key words: composite material, titanium alloy, structural strength, the specific strength

SHAPING TECHNOLOGY

Shashok A. V., Kutyshkin A. V. — Cutting forces valuation at high speed turning operation of the constructional steels

The application of computational and analytical model using the plasticity theory methods, in particular the upper valuation method, for valuation of the cutting force components during high-speed turning is considered. Analytical dependences/expression for the tangential and radial components of the cutting force, taking into account the technological features of the orthogonal turning are adduced. Resistance of the workpiece material deformation is described by the Johnson—Cook model. Blank machining from steel 45 (AISI l045), steel ShX15 (EN-3l), steel 30 (AISI l030) is considered. The calculated values or the cutting forces components compared with the experimental and calculated values obtained through the use of packets LS-DYNA, ABAQUS and SiMPLe and published in the open press. For equivalence degree valuation of the calculating and experimental values of the cutting forces components used the relative error. Analysis of its values showed that calculating and analytical dependences, used in this article, give a better approximation to the experimental values of cutting force components at high-speed turning.
Key words: high speed steels machining, orthogonal turning, cutting force, Johnson—Cook model, the theory of plasticity

Describes an expert system for selection of baseline samples and make recommendations for product improvement at the stage of design and construction. In the basis of the expert system is based on the evaluation, which describe the degree of similarities and differences between estimated and basic products. The magnitude of these estimates is the basis for making the identified product as a base. Developed expert system allows to identify the underlying products not only for the product as a whole but also for individual components and assemblies. The algorithm of functioning of the expert system gives the possibility of developing a computer program for automated determination of basic products.
