Outline of Final Research Achievements

We investigated crystalline structures and mechanical properties of femtosecond laser-irradiated materials such as pure iron (bcc), pure titanium (hcp), pure silicon (diamond), aluminum (fcc), and nickel (fcc). Metastable structures, which did not exist in the initial state, were formed in pure iron, pure titanium, and pure silicon, which had polymorphs in higher temperatures or higher pressures. For all materials, high-density lattice defects were formed and hardness increased in the femtosecond laser-affected zone. We found number of pulses and pulse energy of the femtosecond laser influences the depth of the hardened zone and the increment of the hardness. We succeeded in improving fatigue properties of aluminum plates by shooting femtosecond laser pulses on the surface.
