The present work studies the effect of iron on the microstructural characterization and mechanical properties of Ti12Mo6ZrxFe alloys that fabricated by two different techniques elemental blend (EB) at 600 MPa and mechanical alloying (MA) at 600 MPa and 900 MPa with different sintering temperatures. The Ti12Mo6ZrxFe (x = 1, 2, 3 and 4 wt.%) alloys were investigated to develop new biomedical materials used for dental implant application. The microstructure, residual porosity and the mechanical properties of the sintered Ti12Mo6ZrxFe alloys were investigated by using optical microscopy, X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), Energy dispersive X-ray (EDX), microhardness and bending stress-strain curves. The results indicated that addition of Zr and a small amount of Fe improves the β-phase stability and improving the properties of Ti-Mo alloy. In addition, with increasing the sintering temperatures, the microstructure became more homogeneous for β phase, which decreases in the modulus and strength. The Mechanical alloying allows highly homogeneous composition and particle morphology. Bending strength in EB is much higher than MA techniques. Increasing of compaction pressure during MA technique increases the bending strength and decreases the porosity. Moreover, the Ti12Mo6Zr2Fe alloys exhibited higher bending strength/modulus ratios.

In this study, the effect of WC reinforcing particles on the microstructure and mechanical properties of CuAlMn and CuAlMn-WC alloy produced by powder metallurgy method was investigated by adding 5 %, 10 % and 15 % by volume WC to CuAlMn alloy. Cu, Al, Mn and WC powders of approximately 99.9 % purity with a grain size of 325 mesh were used in the production of the alloys. The samples were produced by hot pressing method at 900 ℃ temperatures under 35 MPa pressure for 6 minutes. Microstructure, phase formation, hardness and corrosion properties of the samples were investigated in detail. Scanning electron microscopy (SEM) was used for microstructure analysis and X-ray diffractogram (XRD) was used for phase formation detection. The hardness measurements of the samples were measured by microhardness measuring device. The corrosion tests were performed potentiodynamic polarization curves of the composite materials in 3.5% NaCl solution. As a result, it has been determined that the mechanical properties of WC reinforcing particles added to CuAlMn matrix increase with increasing volume ratio.

“…Despite existing numerous metals and alloys produced by industry, only a small number of metallic materials can longstanding success as an implanted device [2], since they must fulfill fundamental requirements, such as high corrosion resistance, biocompatibility, and suitable mechanical properties [2][3][4][5][6][7]. Among metallic biomaterials, commercially pure titanium (cp-Ti) and Ti alloys are commonly used as dental and orthopedic devices, due to the high specific strength, low density, high corrosion resistance, and good biocompatibility [8][9][10][11]. The Ti-6Al-4V alloy was created for use in general structures and later adopted for biomedical applications [10].…”

Among titanium alloys with non-toxic elements, the Ti-25Nb-25Ta alloy has good elastic behavior for applications in osseous implants, biocompatibility, and excellent corrosion resistance. The present study aimed to better the biocompatibility characteristics of Ti-25Nb-25Ta alloy modifying its surface through Plasma Electrolytic Oxidation (PEO) treatment. The formed oxide coating is amorphous and composed of two distinct porous formations: smaller hole-shaped pores and larger volcano-like pores. The regions with the formation of smaller pores and in the hole shaped presented the highest atomic percentage of the chemical element phosphorus. Nanoindentation tests have shown that the hardness of the Ti-25Nb-25Ta alloy is slightly lower than the commercially pure grade 2 titanium (a material used as reference), while elastic modulus measurements of Ti-25Nb-25Ta presented more suitable values for implant application (lower values when compared with titanium reference). After PEO treatment there were significant mechanical surface improvements (increased fairly surface hardness and decreased elastic modulus) for application in osseous tissue. Despite the Ti-25Nb-25Ta alloy presented excellent characteristics for applications in hard biological tissues, the PEO treatment better its features.
