Surface profile and microstructure of laser peened Ti-6Al-4V

The surface profile of laser peening with square spots was compared with that of circle spots,and the microstructure of laser peened titanium alloy Ti-6Al-4V in the center of a square spot and at the edge of the square spot was investigated in this paper.The results show that a smaller size crystal...

Zusammenfassung:	The surface profile of laser peening with square spots was compared with that of circle spots,and the microstructure of laser peened titanium alloy Ti-6Al-4V in the center of a square spot and at the edge of the square spot was investigated in this paper.The results show that a smaller size crystal is produced at the edge of square spots because the shearing strain produces nanoscale crystals in laser peening titanium alloy Ti-6Al-4V.
