Article
Full-text available
In this research work, iron-based bulk metallic glasses (BMGs) have been fabricated, characterized and compared with Fe-Si alloy. BMG alloys of composition ((Fe0.6Co0.4)0.75B0.20Si0.05)96Nb4) were synthesized by suction casting technique using chilled copper die. Effect of copper and zirconium addition on magnetic, mechanical, thermal and electroch...

Functionally graded materials (FGMs) of 316L stainless steel (316L) matrix with the reinforcement of hydroxyapatite (HA) were fabricated successfully by a pressureless sintering technique for bioimplants. Hydroxyapatite content was varied among the layers of FGMs up to 20 wt% with 5 wt% gradient. Two types of FGMs were prepared with the same compos...
Article
Three sets of FGMs of stainless steel 316L (SS) reinforced with micro-, nano- and mixed (1:1 mass ratio) hydroxyapatite (HA) were fabricated by powder metallurgy route. The concentration of the HA was varied from 0 to 20. wt% with the increment of 5. wt% in all sets to strengthen the discrete layers of FGMs. The sintered densities along the discret...
Article
In this study, single-phase NbTiZr and NbTiZr(MoTa)0.1 medium-entropy alloys (MEAs) were investigated for their use in biomedical implants. The alloys were prepared by arc melting, and were then cold-rolled, annealed, and characterized in terms of phase analysis, mechanical properties, fractography, and wear resistance. Both alloys showed a single...
Article
In this study, the application of medium- and high-entropy (MoTa)xNbTiZr alloys in biomedical implants was systematically analyzed. The alloy with the best combination of mechanical properties was selected and characterized for in vitro and in vivo response for the first time to examine its biomedical properties. A logarithmic increase in the hardn...
Article
Refinement of harder phase in two-phase MoNbTaTiZr high-entropy alloys (HEA) prepared by powder metallurgy route has enhanced strength and plasticity of the alloy. The MoNbTaTiZr HEA powder used in this study was prepared by hydrogenation–dehydrogenation followed by plasma spheroidization having an inherent dual-phase structure (bcc1 and bcc2) simi...

A novel low-temperature densification method of nanocrystalline calcium hydroxyapatite (HAp) at a temperature as low as 200 °C with no liquid additives is investigated. To understand the underlying mechanism of the low-temperature sintering of hydroxyapatite, two types of lab-synthesized nanocrystalline HAp, dried (110 °C, 12 h) and calcinated (100...
Article
This work showed that the cold sintering process can resolve high-temperature sintering problems that deteriorate mechanical and functional properties. Potential biomedical materials like alumina-hydroxyapatite nanocomposites can decompose into unwanted phases at high temperatures, which reduces their biomedical properties. In this study, hydroxyap...

Nickel titanium (NiTi) shape memory alloys have a vigorous prospective for biomedical solicitations. In this work, electrochemical behavior of hydroxyapatite (HA) coated and thermally oxidized near equiatomic NiTi shape memory alloys was efficaciously investigated for biomedical applications. NiTi samples were spin-coated with laboratory-synthesize...

Questions

Question (1)
Question
Is there any protocol available for in-vivo biocompatiblity testing of metallic implants inside C57bL/6 mice. The purpose of the studies is to evaluate cell response and histology. Articles are available for rats and rabbits but not for this mouse. For instance, in rats, people have implanted specimens into para-vertebral muscle and near the sciatic nerve. They have used 6 mm x 1.8 mm size specimens. What should be the size to do same in mentioned type of mouse. Guidance in this regard will be highly appreciated.
