In industrial practice, various methods of external influences on metal melts are used. For example, vibration processing, exposure to ultrasound, and other physical fields. The main purpose of such influences is purposeful grinding of the metal structure, which contributes to the improvement of mechanical characteristics. The article presents an overview of research on pulse processing of ferrous and non-ferrous melts: processing with pulsed current, electromagnetic pulses and pulsed magnetic fields. The results of the analysis showed that, despite the different methods and devices used for these treatments, their effect on the structure and properties of the cast metal is generally the same. The main effect is observed in the refinement of the macro and microstructure and a simultaneous increase in the strength properties and plasticity. The intensity of the observed effects depends on the characteristics of the equipment used to create the pulses. The main characteristics are: pulse duration, pulse frequency, current amplitude, and power.

“…Based on an analysis of scientific researches performed in the scientific world, the research on the influence of the electromagnetic system on the metal-cutting process can be carried out in the following ways [7][8][9][10][11]: a) cutting tool magnetization; b) magnetization of the workpiece; c) creation of a magnetic field in the cutting zone; d) reversing the magnetization of the instrument; e) pulse magnetic processing; f) magnetization of cutting fluid. One of the important advantages of these methods is their simplicity and the possibility of application in any manufacturing environment.…”

“…The magnetic-pulse method is used for throwing bodies with a mass of 0.1–500 g. It is carried out at speeds of 30–1000 m·s −1 . The principle of converting electric energy stored in the accumulator into a powerful pulsed magnetic field, which affects the processed material in a strictly dosed form, is used in magnetic-pulse material processing technology [ 38 ].…”

Dynamic Alloying of Steels in the Super-Deep Penetration Mode

et al. 2022

View full text Add to dashboard Cite

The dynamic effects observed in collisions represent a specific area of high-energy interaction located at the boundary of mechanics, hydrodynamics, shock wave physics, and alternating high-pressure regions. The paper shows that in the volume of a solid metal body, as a result of dynamic alloying by a high-speed stream of powder particles in the super-deep penetration mode (SDP), fiber structures of altering material arise, forming the framework of the composite material. The stream of powder particles in the metal obstacle following the path of least resistance and the impact of shock waves on particles results in a volumetric framework from the products of interaction between the injected and matrix materials. When using SDP, defective structural elements (channeled)—germs of reinforcing fibers arise. At the subsequent heat treatment, there is an intensive diffusion. The growth process of reinforcing fibers shifts to higher temperatures (as compared to the standard mode), leading to an increase in the bending strength of the fiber material up to 13 times for W6Mo5Cr4V2 high-speed tool steel. As a result of the completion of the growth of reinforcing fibers in the volume of the W6Mo5Cr4V2 high-speed tool steel, the material’s bending strength in 1.2 times is realized. Simultaneously, it provides an increase of wear resistance 1.7–1.8 times.
