Abstract Scope |
Laser forming has been researched as a flexible manufacturing technique for forming sheet metal since the 1980s, but the technology has stagnated because of poor understanding of the relationships between processing parameters and the final geometry and material properties. Recently, it has been shown that incorporation of more realistic property estimates can greatly improve predictability, but major fundamental gaps remain in understanding the metallurgy of laser sheet forming. In this talk, the role of dislocation mechanisms, recovery, and recrystallization are discussed and extended to implications for alloy design. |
