Th e work presents the results of investigations into the structure and phase composition of newly developed high manganese steels of the X98MnAlSiNbTi24-11 and X105MnAlSi24-11 type. The average density of such steels is 6.67 g/cm 3 , which is 15% lower as compared to typical structural steels. An analysis of phase composition and structure allows to conclude that the investigated steels feature an austenitic γ-Fe(Mn,Al,C) structure with uniformly distributed and elongated α-Fe(Mn,Al) ferrite grains on the boundaries of austenite grains and carbides. Examinations by diffraction of back scattered electrons (EBSD) allow to conclude that high-angle boundaries dominate in such steels, having significant influence on mechanical properties. Three types of carbides with differentiated chemical composition and size were identified in steel X98MnAlSiNbTi24-11 with scanning and transmission electron microscopy. κ-(Fe,Mn) 3 AlC carbides, having a regular, face-centered cubic lattice (fcc), were identified in austenite. Transmission electron microscopy examinations have enabled to identify M 7 C 3 -type carbide in ferrite. Nb-and Ti-based complex carbides were identified in steel X98MnAlSiNbTi24-11, both, in ferrite and austenite. (NbTi)C 2 carbide precipitates were confirmed in an X-ray qualitative phase analysis. The size of the above-mentioned carbides is within several to several dozens of μm. An X-ray qualitative phase analysis has confirmed the precipitates of M 7 C 3 carbides in both steels.

“…This passive layer is composed of rutile (titanium dioxide), TiO, and Ti 2 O 3 , which prevent further corrosion of Ti. [ 67 ] As is well known, titanium is the closest of the metallic magnesium electrochemical series, and the electrochemical effects between electrolytes where titanium and magnesium are in contact are minimal. [ 68 ] Therefore, the corrosion rate of titanium magnesium alloy is considered to be lower than that of other metal/magnesium composites.…”

Titanium (Ti) has been widely used in biomedical implants due to its excellent mechanical properties and biocompatibility. However, the “stress shielding” effect greatly limits the application of titanium alloys in medical devices. Studies have shown that the incorporation of bioactive elements into the titanium alloy matrix is an effective way to impart specific biological functions to the material through the sustained release of biofunctional elements. Magnesium (Mg) and its alloys have good bioactivity and are potential candidates for biodegradable metal implants. Ti–Mg composites are of increasing interest for biomedical applications. However, the incompatibility between Ti and Mg, such as immiscibility and large melting point difference, has been a great obstacle in preparing Ti–Mg composites. In addition, the biocompatibility of Ti–Mg metal matrix composites in vivo still needs to be further investigated. Herein, the recent research progress of Ti–Mg composites for biomedical implants is reviewed, focusing on their preparation methods and properties. The preparation methods such as powder metallurgy technology and 3D printing are introduced in detail. In addition, the mechanical and corrosion resistance as well as biocompatibility of Ti–Mg composites are discussed. Based on this, the problems and development prospects of Ti–Mg metal matrix composites are presented.
