Abstract: The invention relates to plastic metal working, more specifically to methods for producing parts of the disk- or shell-type having conical, hemispherical, and also combined parts, such as disk-and-shaft ones. The invention is instrumental in producing large axially symmetric parts from hard-to-work multiphase alloys. The method consists in that the billet is heated in a temperature range above 0.4 m.p. but below the temperature at which a total content of precipitates or an allotropic modification of the matrix of a multiphase alloy is not below 7 %. Then the preheated billet is rolled, while controlling its temperature and the tool load, as well as the rolling speed. Once rolled the billet is heat-treated at a temperature depending on the microstructure of the billet material resulting from rolling. Prerolling preparing of a specified microstructure of the billet material is also described.

Abstract: An ultrahigh carbon steel having a composition of carbon in an amount of from about 0.8 weight percent up to the maximum solubility limit of carbon in austenite, aluminum in an amount of from about 0.5 to about 10 weight percent, an effective amount of a stabilizing element acting to stabilize iron carbide against graphitization, and the balance iron. Preferably, the aluminum is present in an amount of from about 0.5 to about 6.4 weight percent and the stabilizing element is chromium. The steel has excellent ductility and is readily hot, warm and cold worked without cracking. It is particularly useful in superplastic forming operations, and may be processed to a suitable microstructure by any technique which reduces its grain size to about 10 microns or less, and preferably to about 1 micron. Such a very fine grain size is readily achieved with the steel, and the aluminum and stabilizing additions act to retain the fine grain size during superplastic processing.

Abstract: The invention relates to foundry engineering, more specifically to producing a plain bearing antifriction layer by babbiting a bearing pad or base and can be used for producing or repairing plain bearings. The aim of said invention is to improve quality on the a plain bearing antifriction layer. The inventive method for producing the plain bearing antifriction layer consists in babbiting the bearing pad or base and in forcedly cooling at a rate which guarantees the structural uniformity of the thus obtained antifriction layer, mainly by cooling on the cast-in layer side. Said method differs from a known one by that the babbiting of the bearing pad or base makes it possible to obtain a semifinished material of said antifriction layer which is exposed to a plastic deformation by means of a punch under superplasticity conditions in such a way that an antifriction layer is produced, therein the bearing pad or base is used in the form of a matrix.

Abstract: The invention relates to plastic working of metals and alloys, predominantly low-plastic and hard-to-work ones, e.g., nickel-, titanium-, and iron-base high-temperature alloys, and producing billets for parts made by plastic working of said billets. The method comprises thermomechanical processing which is performed beginning with the temperature at which a total content of precipitates or an allotropic modification of the matrix exceeds 7 %, followed by a stage-by-stage decrease of the working temperature down to the temperature at which a stable fine-grained microstructure of the material is obtained, with ratio between the grain size of various phases differing by not more than 10 times, the billet under processing undergoes deformation with a 1.2 to 3.9 times change in the billet cross-sectional area. When preparing billets from nickel-base alloys a stage-by-stage decrease of the working temperature is carried out so as to provide a maximum 14 % gain in the η-phase at each stage. At the end of each process stage a successive annealing of the billet is performed.
