Notes:
Laser forming of metal sheet is a forming technology of sheet without a die that the sheetis deformed by internal thermal stress induced by partially irradiation of a laser beam. In this paper,the bending behavior of common stainless steel 1Cr18Ni9 sheet is studied after being irradiated bystraight line with a Nd:YAG pulsed laser beam. The aim of the investigation is to find out therelationship of the physical behaviors of heat affected zone (HAZ) with the pulse parameters of thelaser. Through the analysis of the fundamental theory of pulsed laser affected, this paper shows theaffected characteristics of metal sheet with pulsed laser forming. The results show that themicrostructure of HAZ of pulsed laser scanned is layered, and the micro-hardness is improved thanthat in matrix. The microstructures show that the deformed grain structure is inhomogeneous, thatcaused the grain sizes and grain orientations in HAZ to become different. By qualitative analysis ofexperimental result, the conclusion obtained may provide basis for theoretical investigation andpossible industrial application of laser forming process in the future
