“…Dissolution of the precipitation structure can be observed for the naturally aged condition and the artificially aged condition of the hardenable aluminum alloy AA6082. The degree of softening as well as the size of the laser heat affected area is dependent on the laser parameters and the ageing condition of the material [16,19,20].…”

“…This feature is similar to laser bending. Laser rapid heating effect on materials of laser bending is studied by a group of scholars [13][14][15][16][17][18]. The research of Shen [16] is typical among these studies.…”

Abstract. Laser bending process of preloaded sheet metal was reviewed on theoretical researches, forming experiments, numerical simulations and material performance studies of formed sheets. Considering the pre-bending platforms that used in the forming experiments can only work on few simple pre-bending types and small sized sheet metals, a large and flexible pre-bending platform was developed by authors. Experiments were done on this platform. The results of experiments showed that different prebending types lead to bending sheet metals into different curved shapes and large sized structure components of flight vehicles can be formed using this process. Based on the current research status, further developments and challenges of this process are discussed.

“…Thus, this process may be useful for forming brittle materials that is easy to fracture by tensile stress and very strong against compressive stress. There are a lot of reports about forming sheets of carbon steel, stainless steel (1) , aluminum alloy (2), (3) , titanium alloy (4) and plastics, these are all ductile material, however, a few researches are performed about forming brittle materials, silicon and glass, by laser forming process (5), (6) . If laser beam is irradiated to thin film metallic glasses, it is considerable that those materials are heated up and become ductile and easy to form plastically.…”

Palladium based thin film metallic glasses were plastically bent by laser forming process. Thin films of Pd 77 Cu 6 Si 17 with a thickness of 0.028mm and Pd 40 Ni 40 P 20 with a thickness of 0.017mm were used for specimen. A 50W YAG laser was employed for forming. Variation of bending angle was investigated by changing working conditions such as laser power, laser operation mode (continuous wave and Q-switch pulsed modes), Q-sw frequency, scanning velocity and scanning number. From the experimental results, both thin films of Pd 77 Cu 6 Si 17 and Pd 40 Ni 40 P 20 were successfully bent for more than 85º. The formed thin films did not crystallize but were amorphous. As scanning number increased, bending angle also increased but increasing rate decreased. When laser power and scanning velocity were changed, bending angle had a peak. When Q-sw frequency was changed, bending angle had a broad peak in Pd 77 Cu 6 Si 17 case, but that was larger as frequency was smaller in Pd 40 Ni 40 P 20 case.
