The mathematical models for forecasting a modification of initial transversal intersection of profile bars under bending and diminution of a thickness of walls for want of to extract of the spherical bottoms are developed. Is investigated influences of hardening of a material for want of deformation, anisotropy of properties leaf of a material, diameter of initial bar on a strain on a thickness for want of to extract of the spherical bottoms. The influence of an infrared radiation and radiation processing on callosity of polymeric composite materials developed recommendations for improving their mechanical performances and acceleration of process of deriving of items is investigated. The scientific fundamentals of deriving of powder materials of high density, manufacturing of items from constructional powders of aluminum alloys because of over plastic state are developed. The diffusion processes are investigated which flow past in a zone of contact of a nickel and niobium for want of to welding, the technology of deriving of their qualitative welded junctions is developed. The certain conditions of hardening of liquid aluminum alloys under an operation under an operation of ultrasonic oscillations with the purpose of improving their mechanical properties. The possibilities of using of generators of plasma, electrical jet engines and their elements for updating metal surfaces are investigated.
