Possibilities of producing stable permanent joints of zirconium-base alloys and stainless steel, used in fuel rods of a number of nuclear reactors, and in sensors and probes of the reactor control instruments are investigated. By the method of solid phase welding joints of zirconium and stainless steel with interlayers from niobium and copper are investigated, which allow the items working in corrosive environment under conditions of thermocycling and alternating loading. Connection between structural changes of the composite and its weakening in the process of action on it of variable thermal fields is studied.
Keywords: zirconium, stainless steel, welding, solid phase, composite material, damping and barrier interlayers, structure, thermocycling, strength
