Metallurgical and Machinability Characteristics of Wrought and Selective Laser Melted Ti-6Al-4V

Rashmi Sinha


This examination work shows a machinability ponder between created review titanium and specific laser softened (SLM) titanium Ti-6Al-4V in a face turning operation, machined at cutting paces in the vicinity of 60 and 180 m/min. Machinability attributes, for example, device wear, cutting powers, and machined surface quality were examined. Covering delamination, attachment, scraped spot, steady loss, and chipping wear instruments were overwhelming amid machining of SLM Ti-6Al-4V. Greatest flank wear was discovered higher in machining SLM Ti-6Al-4V contrasted with fashioned Ti-6Al-4V at all rates. It was likewise found that high machining speeds prompt disastrous disappointment of the cutting instrument amid machining of SLM Ti-6Al-4V. Cutting power was higher in machining SLM Ti-6Al-4V when contrasted with fashioned Ti-6Al-4V for every single slicing pace because of its higher quality and hardness. Surface complete enhanced with the cutting pace in spite of the high instrument wear seen at high machining speeds. By and large, machinability of SLM Ti-6Al-4V was discovered poor when contrasted with the created compound.
