    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 gamma -phase at each stage. At the end of each process stage a successive annealing of the billet is performed.

    Abstract: The invention relates to metal forming using diffusion welding and superplastic forming. Stop-off material is preliminarily applied in a predetermined screen pattern to areas where surfaces of skin and core preforms come into contact. Skin preforms are provided with a groove, and core preform is provided with a slot for mounting at least one tube. A stack is sealed along edges with the exception of where at least one tube is to be mounted. A tube is mounted to be connected to a collector zone, and oxygen and binder of the stop-off material are removed from cavities in the stack. The stack is fully sealed, heated, and the preforms are diffusion-welded in predetermined areas, also along an entrance edge, an exit edge and a peripheral edge. An integral structural preform is given an airfoil shape and subjected to superplastic forming by supplying working fluid into cavities between the skin and core preforms through also at least one tube. The collector zone is disposed on the side of the stack, which corresponds to the peripheral edge of the blade. For mounting one or more tubes for supplying working fluid at superplastic forming, the groove in the skin preforms and the slot in the core preform are provided at a distance from the outer boundary of the entrance edge or exit edge less than L/3, where L is the length of the blade chord along the peripheral edge. It is thus possible to eliminate risk of defects during blade forming without compromising performance characteristics of the blade and increase in labor intensity of producing same.

    Abstract: The invention relates to the electronic engineering and, more specifically, to the fields thereof where the physical phenomenon of electron, or ion-electron, or cold emission is used, and concerns a cold cathode and a method for fabricating the same. Provided is a method for fabricating a cold cathode, according to which a cathode workpiece of a metal or alloy is subjected to severe plastic deformation to transform an initial structure of the workpiece into a fragmented structure comprising fragments of nanometric size or into a mixed structure comprising grains and fragments of nanometric size, characterized in that , after the severe plastic deformation, the cathode workpiece is subjected to a low-temperature annealing for transforming at least part of said fragments into grains of nanometric size at a temperature not lower than the operating temperature T oper of the cathode. The invention is an improvement of the method for fabricating a cold cathode using severe plastic deformation and allows to further enhance efficiency of the cathode via a reduction in the electronic work function value.
