“…For the first experimental base, for testing the theoretical model of the drawing force (1), the process of drawing solid cylindrical billets made of steel 45 (174-187 HB) through a deforming drawplate made of steel 9XC (58-61 HRC) is considered [10]. In this process, the tool used is similar to that of the works [8,9,13,14]; their working surface is strengthened by the creation of a regular micro-relief in the form of single-turn threaded channels with a radius of 1.5 mm, a pitch of 0.5 mm, and an initial depth in the calibration-strip section of 10µm.…”

“…Applied to solid cylindrical profiles, the current methods of processing are systemically and intensively improved through the use of selforganizing tribotechnologies, which include regularizing microgeometry and surface modification of a drawing tool and workpiece, as well as various methods of influence by metal-clad lubricants that allow realizing the fundamental scientific principle "Garkunov-Kragelsky effect, friction without wear" [4][5][6][7][8][9][10][11][12][13][14][15]. This machining method allows to reduce the drawing force by 25-75%, and to increase quality and productivity up to two times.…”

“…This machining method allows to reduce the drawing force by 25-75%, and to increase quality and productivity up to two times. It also allows forming a protective film ("servo-Witte") which contributes to a significant reduction in the cost of drawing tools [9][10][11][12][13][14][15].…”

A mathematical module for predicting and analyzing the drawing force is formed and verified. The process used in the current study is drawing. Geometric parameters of the deformation zone and the "selective transfer phenomenon" are also taken into consideration. The experimental verification is conducted through two tests: In the first test, the experimental blanks are cylindrical rods (steel 45, length 150 mm), and are preliminary machined by turning, and the drawplate made of steel 9xc, are used. Regular micro-relief (RMR) hardens the working surfaces of the drawplate. In the second test, the same conditions are applied except for the samples, which represent solid cylindrical billets made of steel 45 with a complicatedly modified surface layer, including a brass film, regular microgeometry, and a "servo-witte" copper film. As a result, in the first experiment, the discrepancies are in the range of -29.1% up to +23%. In the second experiment, the discrepancies are in the range of +1.38% up to +48.9%.

The cooling rate during fabrication affects the microstructural features and interface strength in metal matrix composites (MMCs). Thus, the present investigation is focused on characterizing the effect of quenching medium on wear and friction response of self-lubricating Al-Cu dual matrix composites. Mica was reinforced in Al-Cu metal matrix composites with the variation of weight percentage as 1%, 2%, 3%, 5%, 8% and 10%. A standard powder metallurgy route was adopted for fabrication. The sintered composites were normalized, and quenched in water, and oil. A pin on disc study was carried to investigate the friction and wear behavior of normalized, oil quenched, water quenched and as-prepared (green) composites. The results revealed that oil quenched composites exhibited the lowest friction coefficient and highest wear loss. The highest friction coefficient of ~0.8 was observed for normalized composites, whereas the highest friction coefficient for water quenched composites was ~0.6. The oil quenched composites exhibited about 8 ~ 15 times higher wear loss as compared to normalized and water quenched composites. Worn surfaces were analyzed under a scanning electron microscope to know the dominant wear mechanisms. The developed composites find potential applications in automotive industry such as pistons for petrol and diesel engines.
