Mararenko K.V. On the Production of Mottled Cast Irons with Ausferritic Structure from Cast State
The way of manufacture carbidic austempered ductile iron, having tall strength and hard-wearing properties. The structure providing a high level of properties to products, is gained from a molten condition, due to overlapping processes of solidification and a heat treatment. The technology is distinguished with tall pliability and stability of results.
Key words: CADI, mottled cast iron, ausferrite, wear resistance, "hot" shakeout, isothermal hardening.

Sapchenko I.G., Zhilin S.G., Evstigneev A.I. Preferences of application and peculiarities of projecting of press-accessory in process of porous investment pattern manufacturing in precision casting
Preferences of method of producing precision casts against porous investment patterns are under consideration at article. Such models are producing by press forming of powders of homogeneous and heterogeneous lost waxes with different flow rate. Variants of model shaping are given subject to elastic aftereffect, which arise at pressed material. Recommendations on press mold projecting for models production by method of model composition powder pressing are given.
Key words: lost wax powder, cast, dimensional-geometrical precision, press mold, porous, investment pattern
Levshin G.Y., Pavlyuk K.I. On the Thermophysical Characteristics of Magnetically Soft Molding Materials and Magnetic Molds
The reasons of unsatisfactory accuracy of definition of thermophysical characteristics magnetic soft forming materials and the magnetic mould, included in settlement formulas are considered and established. Linear mathematical models of their dependence on temperature are offered.
Key words: magnetic mould, magnetic soft forming materials, thermophysical properties, specific, heat capacity, heat conductivity, thermal receive, temperature conductivity.
Ivanko Е.К. То a question on bases of a centrifugal casting
In work are submitted, executed on the basis of laws of hydrodynamics, theoretical researches of factors of involving of liquid metal in rotation and his(its) movement in a ring stream. It is shown, that the ring stream of liquid metal in the rotated form represents the unsteady movement. Process of involving of liquid metal in rotation does not stop down to occurrence of a firm phase of metal.
Key words: centrifugal casting, hydrodynamics, liquid metal
