Metal deformation under conditions of isothermal and near-isothermal deformation is characterized by an increase in plasticity compared to plasticity during processing in a cold tool. This is due to the lower strain rate, the lower limit of which is limited only by the productivity of the process. As a result, the time for "filling defects" that occur during metal deformation increases, the thermal stress in the work piece volume decreases, and the deformation becomes more uniform. In this work, a technique for conducting experimental studies has been developed, covering an extended range of tasks for determining the technological parameters of rolling billets from aluminum alloys under conditions of isothermal and close to it deformation.

To determine the technological parameters and thermomechanical characteristics, an installation for billet rolling under conditions of isothermal and close to it deformation is proposed. In order to ensure the rigidity of the rollers and maintain a constant center-to-center distance during the deformation process, the installation is made according to the type of two-bearing forging rollers. To maintain the temperature of the workpiece and heat the working tool (roller dies directly mounted on the rollers), the unit is equipped with a heating device installed on the back side.

On the basis of the analysis of the results of experimental studies, the optimal technological parameters of rolling blanks from aluminum alloys at variable temperatures, speeds, degrees of deformation and development of the technological process were determined. Technological recommendations for the calculation of gauges are proposed and a technical task is developed for an industrial sample of equipment for rolling blanks in conditions of isothermal and near-isothermal deformation, including work during traditional rolling without heating of rolling dies.


Keywords: hot deformation, rolling of workpieces, aluminum alloys.

History of journal:

In June 1994 the 2nd International Scientific and Technical Conference "Application of vibrations for technological purposes" was organized on the basis of Vinnytsia State Agricultural Institute. Leading experts in this field, noting the significant contribution to the school of Vibration Engineering under the leadership of P. S. Bernyk, proposed to create a professional all-Ukrainian scientific and technical journal "Vibration in engineering and technology..The journal was foundedat Vinnytsia State Agricultural Institute and P.S. Bernyk was elected to be the chief editor .
For all these years (since 1994) theJournal "vibration in engineering and technology" published  94 issues wherestudy of vibration effects, the creation of progressive energy saving technologies and equipment for their implementation were highlighted.
Currently Kaletnik H.M  PhD , professor, academician NAAS is the chief editor of the "Vibrations in engineering  and Technology"
The journal "Vibration in Engineering and technology", which has no analogues on the territory of Ukraine, is well known abroad.
