“…Some of these devices are dedicated to maintaining structural stability and aligning bone fragments for a finite time during the healing process of fractures, so that they became temporary devices [ 4 ]. Traditionally, such temporary osteosynthesis devices are made from inert metallic materials, but this approach requires a second surgical procedure to extract the device at the end of the healing process [ 1 , 2 , 3 , 4 , 5 , 6 , 7 ]. Rahim et al [ 2 ] set some important requirements for degradable orthopedic implants to allow the healing of broken bones, like high biocompatibility, tissue friendly self-degrading, and minimal stress-shielding effects.…”

In recent years, biodegradable Mg-based materials have been increasingly studied to be used in the medical industry and beyond. A way to improve biodegradability rate in sync with the healing process of the natural human bone is to alloy Mg with other biocompatible elements. The aim of this research was to improve biodegradability rate and biocompatibility of Mg-0.5Ca alloy through addition of Y in 0.5/1.0/1.5/2.0/3.0wt.%. To characterize the chemical composition and microstructure of experimental Mg alloys, scanning electron microscopy (SEM), energy-dispersive spectroscopy (EDS), light microscopy (LM), and X-ray diffraction (XRD) were used. The linear polarization resistance (LPR) method was used to calculate corrosion rate as a measure of biodegradability rate. The cytocompatibility was evaluated by MTT assay (3-(4,5-dimethylthiazole-2-yl)-2,5-diphenyltetrazolium bromide) and fluorescence microscopy. Depending on chemical composition, the dendritic α-Mg solid solution, as well as lamellar Mg2Ca and Mg24Y5 intermetallic compounds were found. The lower biodegradability rates were found for Mg-0.5Ca-2.0Y and Mg-0.5Ca-3.0Y which have correlated with values of cell viability. The addition of 2–3 wt.%Y in the Mg-0.5Ca alloy improved both the biodegradability rate and cytocompatibility behavior.

The use of titanium and titanium-based alloys with applications in implantology and dentistry has made remarkable progress in the promotion of new technologies and new materials that have been developed in recent years. This is justified thanks to their excellent mechanical, physical, and biological performance. Today's generation promotes new titanium alloys, with nontoxic elements and long-term performance and without rejection of the human body. This book chapter describes new original compositions of Ti-based alloys for medical applications, with improved properties compared to existing classical alloys (C.p. Ti, Ti6Al4V, CoCrMo, etc.). The addition of nontoxic elements such as Mo, Si, Zr, and Ta brings benefits as reduced modulus of elasticity, increased corrosion resistance, and improved biocompatibility.

“…Molybdenum is an element that has a lower harmful effect (toxicity level) compared to any other elements, such as Co, Ni, and Cr. Addition of molybdenum element on titanium alloy was able to promote chance to be applied as bioimplant, especially from the perspective of mechanical properties [25]. It can enhance the ultimate tensile strength (UTS) but decrease the Young's modulus to avoid stress shielding phenomenon [26].…”

This paper aims to find the phase transformation of Ti-3Mo at% applying solid solution treatment. Methodology: the Ti-3Mo specimens were produced by using arc melting furnace followed by homogenization in vacuum capsule at 1200 o C for an hour. After that, the specimens were hot-rolled into 1.5 mm in thickness. Then, the specimens were solid solution treated at 1000 o C for 10 minutes followed by rapid cooling (quenching). Phase and microstructure observation were conducted using XRD and optical microscope. TEM was also used in this study. Vickers hardness test was applied to confirm the homogeneity of the specimens. Results: It was found that α''-martensite titanium with orthorhombic cell structure was the main phase of Ti-3Mo after solid solution treated followed by rapid cooling. Analysis of volume indicated that α''-martensite unit cell had similarity to β-phase titanium but 0.792% greater in volume. Further heat treatment needed to be applied in order to ensure the formation of β-phase in the specimen. Applications: This study shows that the presence of molybdenum element in titanium alloys can prevent the formation of α hexagonal close packed (hcp) phase at room temperature.
