New Trend in Material Science : LAP Lambert Academic Publishing : 9786203041897 : 6203041890 : 20 Feb 2021 : New methods for laser interaction with material specially alloys, the effect of laser irradiation on microstructure and mechanical properties are discussed. Development of new techniques to treat nanomaterials as the the first treatment process of nano and micro particles, industrial unit for hardening and treatment of nano-materials and micrometers to improve their physical, chemical and mechanical properties by exposing them to laser radiation. The treatment process is carried out through the laser treatment industrial unit. It is composed of circular metal base with motor, rectangular holder, moving sides. The sample installation cavities which are metal joints that widen and shrink according to sample dimensions by incorporating the cavities vertically and moving the sides, the unit has black front and back barrier to prevent lasers with bottom cavity to store the black barr
