摘要：
Experiment was carried out to reveal the plastic deformation of pre-elastic-stretched titanium alloy strip partially subjected to localized heating via Laser beam irradiation. The temperature profile in the strip under Laser beam irradiation was computed with finite element method. The strain redistribution and localized plastic deformation were analyzed by a one-dimensional model. The results indicate that both the pre-strain level and the ratio of the length of heated range to the total effective length of the strip influence obviously the final plastic strain.
