Changes in the structure of metallic alloys at a thermocycling from the laser influence up to over-eutectic temperatures

Researches of influence of thermocycling by laser radiation up to over-eutectic temperatures on structure of a two-componental alloy of Cu-Zn system of brass L62 are carried out. It is established that thus in volume of samples from copper-zinc alloy L62 in thickness of 50 micrometer there is a formation of the submicro- and nanoporous structure leaving on external surfaces of a sample. This layer has spongy finely divided structure. A nanopores has close to equiaxed a form and uniting, forms submicropores.
