Rapid Oxynitriding of Ti–6Al–4V Alloy by Induction Heating in Air

In this study, a rapid oxynitriding technique based on induction-heating was developed for the titanium alloy Ti–6Al–4V, and its effects on surface characteristics of the alloy were investigated. The surface microstructures of the alloy were characterized by employing a scanning electron microscope, electron back-scatter diffraction, X-ray diffraction and nano-indentation tests. Induction-heating in air for 60 s caused the formation of a...
