The aim of this paper is to map the corrosion fatigue characteristics of Ti-6Al-4V alloy through the evaluation of the corrosion fatigue initiation and failure mechanisms. The study included the effect of the stress concentration factor at very high Kt values and the role of different inert or corrosive environments. This alloy is widely used in naval-structures and aero-engine communities and ...

In the presented work, formation of anodic oxide film on Ti-6Al-4V ELI (Extra Low Interstitial) alloy in 0.02 M trisodium phosphate (Na

The quaternary Ti-Nb-Zr-Ta (TNZT) alloy was successfully cast-fabricated with the objective to be used in medical field. Samples’ microstructure compared CP-Ti and Ti-6Al-4V (control samples) related corrosion, ion release biological properties. As-cast TNZT formed large β grain sizes (285 µm) ultrafine α of (11 + 1.45 µm 0.74 µm. Hardness flexural elastic moduli (94 HV 43 GPa) came close struc...

Biological fixation of uncemented endosseous implants requires the apposition of bone onto implant’s surface in a process named osseointegration [1]. The present study examined bone tissue response to Ti-6Al-4V alloy implanted into the rat femurs over a long time range (3 days to 6 months). The progression of implants fixation in the cancellous bone of distal epiphysis and within the medullary ...

A recently developed ultra-hard boride-based material, AlMgB14, has been fabricated into a standard cutting tool geometry (TPG-222) and tested using single-point turning of Ti-6Al-4V. The initial testing was conducted to compare this new cutting tool’s performance relative to a WC-Co cutting tool. During the tests the boride-based inserts suffered catastrophic failure for a wide range of cuttin...
