Titanium alloys are used in different industries like biomedical, aerospace, aeronautic, chemical, and naval. Those have high requirements with few damage tolerances. Therefore, they necessary to use materials that present fatigue, mechanical, corrosion resistance. Although Ti-alloys material performance, exposed marine industrial environments. This research shows the behavior of three titanium...

Asymmetric incremental sheet forming (AISF) could significantly reduce costs incurred by the fabrication of complex industrial components with a minimal environmental impact. The AISF experiments were carried out on commercially pure titanium (Ti-Gr2), Timetal (15-3-3-3) alloy, and Ti-6Al-4V (Ti-Gr5) alloy. A special testing geometry was used to characterize the titanium alloys properties from ...

PURPOSE The aim of this study was to investigate the cytotoxicity in human gingival fibroblast by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and corrosion behavior by potentiodynamic polarization technique of commercially pure titanium (Ti 12) and its alloy Ti-6Al-4V (Ti 31). MATERIALS AND METHODS In the present in vitro study, cytotoxicity of Ti 12 and Ti 31 in ...

Micro-milling of Ti–6Al–4V using uncoated and cBN coated tungsten carbide micro-end mills are conducted; surface roughness, burr formation and tool wear are measured. Effects of machining parameters on surface roughness, burr format...

OBJECTIVE The purpose of this study was to determine the microtensile bond strength of various resin composite/adhesive systems to alumina particle abraded Ti-6Al-4V substrate after aging for 24h, 10 days, and 30 days in distilled water at 37 degrees C. METHODS Four laboratory resin composite veneering systems (Gradia, GR; Solidex, SOL; Ceramage, CER; and Sinfony, SF) were bonded to 25 mm dia...

A novel two-step bonding of Ti-6Al-4V/Si 3 N 4 joint was developed with Nb interlayer as residual-stress reliever via low-pressure transient-liquid-phase (TLPB) Ti-6Al-4V/Nb side prior to active-metal brazing Nb/Si side. While 1.75 mass% Ti in a 50-µm-thick CUSIL-ABA® filler sufficient for sound at when brazed 1103 K 10 min, one-step-brazed joints area × mm 2 were prone failure the due brittle ...

Ti–6Al–4V scaffolds were fabricated by powder metallurgical space holder technique in this research. The most added magnesium (Mg) powder was evaporated and a skeleton of Ti-6Al-4V alloy was produced. For this purpose Ti-6Al-4V and Mg powders mixture compacted in a steel die by applying uniaxial pressure of 500 MPa before sintering the green product in a sealed quartz tubes at 900 °C for 2 hour...

This study investigated the microstructure evolution of TiC/Ti-6Al-4V matrix composite produced using a 1073 nm continuous wave (CW), IPG Ytterbium fibre laser. The influence thermal gradient, overlap, and re-melting previous layers on TiC/Ti6Al4V samples was analyzed scanning electron microscope (SEM). showed that are composed undissolved TiC, in-situ TiC (eutectic primary TiC), α Ti β Ti. Whi...

Ti-6Al-4V titanium alloy has great application in medicine and military industries due to its capabilities, namely high strength to weight ratio and corrosion resistance. In the current research, the effect of aging treatment on microstructure and wear behavior of Ti-6Al-4V titanium alloy was investigated. Pin on disk wear test was applied to assess the wear behavior. Specimens were first solut...
