Heterogeneous microstructure of the bonding zone and its dependence on preheating in hybrid manufactured Ti-6Al-4V
نویسندگان
چکیده
Hybrid manufacturing (HM) Ti-6Al-4V components combining the advantages of forging and additive were achieved. The bonding zone HMed component joins substrate manufactured its α′-α/α′/αm-α/β heterogeneous microstructure was attributed to distinguishing cooling rate pseudo-isothermal annealing temperature. phase transformation mechanisms clarified with a numerical simulation model for thermal analysis. Moreover, preheating manipulate size, volume fraction distribution α′/αm/α phases tailor microstructure.

LASER 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 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 کاملEffect of Gas-Diffusion Oxynitriding on Microstructure and Hardness of Ti-6Al-4V Alloys
The commercially available titanium alloy, Ti-6Al-4V, was oxynitrided in the deoxygenated nitrogen gas at high temperatures followed by cooling in oxygen-containing nitrogen in order to analyze the influence of oxynitriding parameters on the phase modification, hardness, and the microstructural evolution of the oxynitrided coating. The surface microhardness of the oxynitrided alloy increased du...
