Biodegradable magnesium alloys have emerged as promising alternatives to permanent metallic implants due to their unique combination of mechanical compatibility with bone and complete resorption, addressing the persistent issues of stress shielding and secondary removal surgeries. This review critically examines the historical development of magnesium-based biomaterials, highlighting advances in alloy design, manufacturing processes, and surface engineering that now enable tailored degradation and improved clinical performance. Drawing on recent clinical and preclinical studies, we summarize improvements in corrosion resistance, mechanical properties, and biocompatibility that have supported the clinical translation of magnesium alloys across a variety of orthopedic and emerging medical applications. However, challenges remain, including unpredictable in vivo degradation kinetics, limited long-term safety data, lack of standardized testing protocols, and ongoing regulatory uncertainties. We conclude that while magnesium-based biomaterials have advanced from experimental concepts to clinically validated solutions, further progress in personalized degradation control, real-time monitoring, and harmonized regulatory frameworks is needed to fully realize their transformative clinical potential.

The sequence and development of the life cycle of a machine-building product are described. Metals recycling, specifically hard alloys, is considered one of the important economically profitable directions of production development. The evaluation of the efficiency of such a method is given in the example of the explosive processing of hard alloys.

It is shown that high requirements of mechanical strength, corrosion resistance and minimal losses at magnetization reversal during the passage of alternating current are imposed on the connecting elements of electric overhead lines. Sometimes the diameters of the wire ends are increased for the convenience of inserting them into connectors. In pressure treatment this process is known as dispensing. During dispensing the wall thickness of the edge sections decreases and, under certain conditions, destruction of the workpiece may occur in the form of a crack at the end. Besides, overestimated dispensing coefficients result in a loss of stability of the non-deformable part. To avoid these undesirable phenomena and reduce the production cost of tubular connecting elements, the authors of the paper analyze the factors that cause rejects during plastic deformation. It is shown that the yield point of the material and the shell thickness are the workflow main parameters that have a prevailing effect on the loss of stability of the non-deformable part of the workpiece. By changing them, it is possible to achieve the manufacture of high-quality connectors for electrical wires.

Issues of increasing the FDM products strength due to the oscillations field imposition to the extrusion zone at the time of laying out the plastic are considered, which makes it possible to densify the laying out, increase the strips plane of the adhesive interthread and interlayer contact, and precede the extrusion of plastic beyond the laying out zone. Process simulation was performed in order to determine the rational processing modes and to establish the corresponding oscillations amplitudes and frequencies. The phenomena of plastic melt and extrusion, the temperature fields distribution on the surface of the contact strips formation, the drive dynamics during the movements algorithmic development in unsteady oscillatory motion by feed drives are taken into account. Experimental tests the proposed algorithmic solutions were carried out, a number of product demonstrators were made in the test cube form (20x20x20 mm) and a blade for tensile testing (160 mm). It is shown that due to the oscillations imposition at the extrusion zone, it is possible to increase the tensile strength of products by 15-18%, and a greater increase is observed in the plane of the work table. The possibility of achieving strength parameters approximately corresponding to the filament strength is shown. Further research with reinforced plastics and PEEK group plastics is recommended.
