Precious metal based bulk metallic glasses (BMGs) exhibit enhanced mechanical strength, high corrosion resistance, and excellent superplastic forming capability. Such property combination makes them particularly attractive for medical, space, and watchmaking applications. In addition, for medical applications, the Cu and/or Ag bearing BMGs could have an antibacterial effect through a...

Field-assisted sintering technique (FAST) was used for fast prototyping of Ti-Nb-Zr-O based alloys from blended elemental powders. These alloys are promising materials for application as load-bearing implants as they possess high strength and low elastic modulus. Precise optimization of the composition of these quaternary alloys is crucial for fine tuning of β phase stability and, in...

Ti-Cu based metallic glass Ti47Cu38Zr7.5Fe2.5Si1Sn2Ag2 at% with biocompatible elements was selected with better glass forming ability due to the selection of good glass formers and mechanical properties with lower young’s modulus 100GPa[1]. Modifications to the existing combinations was made to develop a master alloy with Ti42Cu40Zr8.5Fe2.5Si2Sn2Ag3 at% composition and the alloy ingot was Arc...

Bulk Metallic Glasses (BMGs) propose a set of outstanding properties due to their inherent amorphous structure. Compared with their crystalline counterparts, BMGs usually display higher yield strength and fracture limit, good corrosion resistance and increased processability. In particular, Ni-free Ti-based BMGs show excellent biocompatibility besides attractive mechanical properties. These...

The present study investigates the influence of thermomechanical (TM) processing conditions on microstructure and mechanical properties of new Ti-Nb-Ta-Zr (TNTZ) alloy, by SEM (scanning electron microscopy), tensile and microhardness testing techniques. The TNTZ alloy was produced in cold-crucible levitation melting starting from high-purity constituent elements. The TNTZ alloy was...

Magnesium (Mg) alloys are renowned for metal implant applications due to their versatility in mechanical strength, biodegradation, ability in supporting mineralization and enhancing chondrogenesis. Over time bones and joints lose their protective cartilage by wear off leading to long term degenerative joint disorder called osteoarthritis (OA). OA symptoms include joint pain and stiffness...

Metastable beta Ti alloys are considered as perspective materials for the new generation of body implants. Their strength can be substantially improved by addition of interstitial oxygen to fit the requirements for implant materials (strength at least on par with Ti-6Al-4V). By adding 0.7 wt.% of oxygen, the yield strength of 1000 MPa can be achieved in the beta quenched condition while the...

Implant-associated infections caused by bacterial biofilms represent a serious clinical problem. Being highly resistant to conventional antibiotic treatments, it becomes urgent to find new solutions to tackle this form of infection, such as innovative materials with effective antimicrobial properties.

Binary TiNb alloys are promising implant materials due to their low stiffness, excellent...
