“…The relationship between the average recrystallization grain size (d) and the Zener-Hollomon parameter (Z) during dynamic recrystallization is given by -lnd= A + Bln Z. Based on the present TC-ECAE process with extrusion temperature 400℃,average accumulative strains, strain rates and Z parameters of the AZ61 increase with the development of TC-ECAE process [21][22][23]. It can be found that the accumulative strains increase with the extrusion advancing, so the grains will be re ned consequently.…”

Due to demand of strong toughness of thin walled tube, and good secondary forming properties and high-precision dimension, New plastic forming method should be researched to achieve a complete filling, uniform deformation and microstructure evolution during forming process.To obtain the deformation mechanisms of a new composite extrusion for thin walled tube fabricated by tube corrugated equal channel angular extrusion has been researched which is shorten as “TC-ECAE” in this paper. Finite element DEFORMTM-3D software to investigate the plastic deformation behavior of magnesium billet during TC-ECAE process has been employed. Computed parameters including workpiece material characteristics and process conditions have been taken into consideration. The pridictions of strains distributions and damage distributions and effective stress distributions and flow velocities distributions and microstructures evolutions have been explored. The results proved that the TC-ECAE process is a forming method for magnesium alloy tube which is suitable for large scale industrial application. The TC-ECAE process would cause serve plastic deformation and improve the dynamic recrystallization of magnesium alloy during TC-ECAE process.

The paper, based on a review of modern literature, highlights the features of the processes of magnetic pulse processing of metals in traditional schemes of technological processes of modern industrial production. New directions of their development are noted, which provide for the transformation of the natural forces of repulsion of the metal of the processed object into the forces of magnetic-pulse attraction while reducing the operating frequencies of the existing fields. The physics of Lenz-Joule heat dissipation is described, the result of which is the induction heating of conductors by Foucault currents in an external electromagnetic field. Examples of the use of induction heating in modern industry are given. Schemes of practical realizationof preinduction heating are offered, which allow to use both autonomous devices for eddy current excitation and stationary connection for the same purpose of additional power source. The possibility of increasing efficiency by increasing the ductility of the metal when heated is noted, as well as its possible limitations associated with increasing the active resistance of metals during the growth of Lenz-Joule heat dissipation. It is offered to use the received results at a choice of design decisions for elements of new schemes of the equipment of magnetic pulse processing of metals.
