Influence of Pulse Current Modes on Ultrafine-Grained Titanium Mechanical Tensile Behavior DOI: 10.22184/2499-9407.2024.36.3.40.46
Influence of pulse duration and pulse current density on deformation behavior and mechanical properties in tension of ultrafine-grained technically pure Grade 4 titanium is presented. The pulse current modes, which contribute to increase of tensile ductility without changing the microstructure of considered material have been studied. The minimum pulse duration necessary for the manifestation of the electroplastic effect is shown.

Information and Technological Fundamentals of a Computed Design System of Multi–Level Basic Group Technology. Part I DOI: 10.22184/2499-9407.2024.36.3.58.65
The paper describes information and technological principles and methodology multitier basic technology system design, used top-down and bottom-up methods designing “analysis-synthesis” of construction-technological information. Application of the method of synthesis for solving enumeration technically possible integrable transitions, and set the position on professional PCs with proper table-filling technology matrix of average skill enable optimal for the existing production group process of machining precision turned parts simple and complex shapes. The system allows you to formalize the decision-making process at the optimal level for the synthesis of group tool adjustments, selection of a unified tool model and cutting modes with a real forecast of cutter life. The advantages of the proposed approach compared to traditional ones are a significant increase in the quality of the developed group technology and a sharp reduction in the time required for technological preparation of modern high-tech precision production.
