Metallic wires are critical components for various clinical applications, including orthopedic fixation, surgical staples, K-wires, and guide wires. They can also be knitted or woven to fabricate cardiovascular stents and bone scaffolds. [1][2][3] Conventionally, such devices are made by metals such as stainless steel (SS), titanium (Ti) alloys, and cobalt-chromium (CoCr) alloys because of their excellent corrosion resistance and superior mechanical properties compared to local biological tissues. [4] However, the nondegradability of these alloys can require a secondary surgery, and their high stiffness may enable stress shielding. [5,6] In contrast, polylactic acid (PLA), poly(lactide-co-glycolide) (PLGA), and polycaprolactone (PCL) possess biodegradability, which can avoid the need for a second surgery. However, the acidic nature of their corrosion byproducts can lower the local pH of the tissue microenvironment, resulting in elevated inflammatory responses. [7,8] Furthermore, they possess weak mechanical properties, which limit their use in load-bearing applications. [9,10] Magnesium (Mg) and its alloys offer a third type of material that possesses multiple promising properties. First, Mg is an essential element for human metabolism, and it has shown sufficient biocompatibility. [11,12] Second, Mg alloys have elastic moduli (40-45 GPa) and yield strengths (100-600 MPa) closer to those of natural bone (5-23 GPa, 35-283 MPa) than common, inert metallic implants, [13,14] effectively reducing stress concentrations around host tissue as well as stress shielding. [15] More importantly, Mg can degrade in the human body in a safe and controlled manner, thereby reducing the need for second surgeries to remove implants. [14,16,17] Currently, successful clinical trials of Mg-based alloys have been reported for orthopedic applications in Germany, [18] China, [19] and South Korea. [20] Conventional, cold-worked (CW) techniques are considered the most promising methods to fabricate fine Mg wires (diameter <1 mm), given their low cost and efficiency. [21] However, these processes are challenging for magnesium-based materials due to their hexagonal close-packed (HCP) crystal structure that has limited slip systems at room temperature. [22][23][24][25][26][27] In some cases, alloying can increase room-temperature ductility. Fine wires made from an Mg-aluminum (Al) alloy have been widely reported, [28][29][30][31][32][33][34] but accumulations of Al in the body are a concern as they can cause neurological disorders such as Alzheimer's disease and dementia. [35] Other elements, such as zinc (Zn), [36,37] silver (Ag), [38] and calcium (Ca), [39,40] have also been included in Mg alloys. For example, M. Zheng et al. [41] first reported

“…Due to the fact that the AZ31 alloy undergoes fast hardening, it was necessary to perform inter-stage heat treatment. The process of selecting the heat treatment parameters, the drawing die shape and the magnitude of unit reduction is described in reference [7][8][9]. A scheme of the process of wire drawing and heat treatment is shown in Table 2.…”

The formability of magnesium alloys is the subject of efforts undertaken in many research centers due to their outstanding mechanical, plastic, and above all, physical properties. For this reason, magnesium alloys have become an important material which finds broad possibilities for application in many industries: automotive, electronics, aerospace and so on.The paper presents an analysis of changes in structure of AZ31 magnesium alloy wire cold-deformed in the drawing process using interoperate heat treatment. Microstructure observations of the wire by means of optical microscopy were performed in initial state, after each drawing process, and before and after heat treatment. The studies regarding the impact of selected variants of deformation on microstructure were also carried out at the scanning electron microscope (SEM).

The paper presents the results of the experimental tests of Al-Cu bimetallic bars rolling process in multi-radial modified passes. The bimetallic bars consist of aluminium core, grade 1050A and copper outer layer, grade M1E. The stocks were round bars with diameter 22 mm with a copper layer share of 15 and 30%. As a result of rolling in four passes, bars of a diameter of about 16.0 mm were obtained. A bimetallic stock was manufactured using an explosive welding method. The use of the designed arrangement of multi-radial modified stretching passes resulted in obtaining Al-Cu bimetallic bars with the required lateral dimensions, an uniform distribution of the cladding layer over the bar perimeter and high quality of shear strength between individual layers.Keywords: bimetallic bars, explosive welding, groove-rolling, connection quality W pracy zamieszczono wyniki badań doświadczalnych procesu walcowania prętów bimetalowych Al-Cu w wielopromieniowych modyfikowanych wykrojach wydłużających. Pręty bimetalowe Al-Cu składały się z aluminiowego rdzenia w gatunku 1050A oraz miedzianej warstwy platerującej w gatunku M1E. Udział miedzianej warstwy platerującej w przekroju poprzecznym pręta wynosił 15 i 30%. średnica początkowa prętów bimetalowych wynosiła 22 mm, a średnica końcowa po walcowaniu w czterech przepustach wynosiła 16 mm. Wsad bimetalowy otrzymano z wykorzystaniem metody zgrzewania wybuchowego. Zastosowanie zaprojektowanego układu wielopromieniowych modyfikowanych wykrojów wydłużających zapewniło otrzymanie prętów bimetalowych Al-Cu o wymaganych wymiarach poprzecznych, równomiernym rozkładzie warstwy platerującej na obwodzie pręta oraz wysokiej wytrzymałości złącza na ścinanie.
