Effect of fast-frequency pulsed waveforms on the microstructure and mechanical properties of Ti–6Al–4V alloy welded by FFP-TIG

Journal of Materials Research and Technology, 2022
Ti–6Al–4V alloys have been widely adopted because of their good mechanical properties. TIG welding is a common method for Ti–6Al–4V alloys. However, the high heat input of conventional TIG can lead to a coarsening of grains within Ti–6Al–4V and thus a ...
