Microstructural Evaluation of Ti-6AL-4V Alloy during Hot Deformation
Among the titanium alloys, Ti-6Al-4V is the most widely used. In the present work, the uniaxial hot compressive behavior of Ti-6Al-4V has been investigated under constant strain rates. A series of dilatometery experiments were carried out to determine the transformation temperatures at different cooling rates. Specimens were homogenized at 1050 °C for 10 minutes followed by fast cooling to dif...
متن کاملFatigue of Ti-6Al-4V
Metallic biomaterials have essentially three fields of use; these are the artificial hip joints, screw, plates and nails for internal fixation of fractures, and dental implants. Any of these devices must support high mechanical load and resistance of material against breakage is essential. High mechanical properties are needed for structural efficiency of surgical and dental implants. But their...

متن کاملLASER SURFACE PREPARATION FOR ADHESIVE BONDING OF Ti- 6Al-4V
Adhesively bonded structures are potentially lighter in weight than mechanically fastened ones, but existing surface treatments are often considered unreliable. Two main problems in achieving reproducible and durable adhesive bonds are surface contamination and variability in standard surface preparation techniques. In this work three surface pretreatments were compared: laser etching with and ...
متن کاملPROCESS CONTROL AND DEFECTS IN Ti-6Al-4V ADDITIVE MANUFACTURING, USING PLASMA TRANSFERRED ARC (PTA) TECHNIQUES
Defects during Plasma Transfer Arc (PTA) beam fusion additive manufacturing (AM) processing of Ti-6Al-4V, including lack of fusion, porosity variations, and solidification cracking, have been monitored using near infrared (1.62 μm) imagery at 300 Hz, 300 μm spatial resolution and melt pool sizes of greater than 12μ. The temperature evolution exhibits a periodic temperature modulation of more th...
