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...

most of the materials used in the industry of aero-engine components generally consist of titaniumalloys. advanced materials, because of their excellent combination of high specific strength, lightweight and general corrosion resistance. in fact, chemical wear resistance of aero-engine alloyprovides a serious challenge for cutting tool material during the machining process. the reductionin cutt...

In this work, surface Ti-Cu-Al-V alloy was synthesized by compression plasma flows impact on Ti-6Al-4V titanium preliminarily coated copper. The treatment of Cu/Ti-6Al-4V samples carried out three pulses generated in the nitrogen atmosphere (energy density absorbed varied range 26-43 J/cm2 per pulse). phase and elemental composition, structure, microhardness friction coefficient formed were inv...

Due to recent concern about allergic and toxic effects of Ni ions released from TiNi alloy into human body, much attention has been focused on the development of new Ni-free, metastable beta-type biomedical titanium alloys with a reversible phase transformation between the beta phase and the alpha'' martensite. This study investigates the effect of the stress-induced alpha'' martensite on the m...

Titanium alloys have found increased applications in various industrial sectors. One of the critical issues in quality control is the weld penetration during welding. In the present paper, tungsten inert gas (TIG) welding of Ti-6Al-4V alloy with and without an activating flux was conducted. The effect of the activating flux on Ti alloy welding was investigated. A data acquisition system was use...
