FIELD: metallurgy. ^ SUBSTANCE: work-piece out of aluminium or alloyed aluminium and of base metal or alloyed base metal is produced by placing insertions out of aluminium or alloyed aluminium in form of rods, sheets, tubes or wire in closed cavities of base metal or alloyed base metal. The cavities are sealed. Further, there is performed hot deformation of the work piece at temperature exceeding temperature of aluminium melting and equal to temperature of base material deformation. ^ EFFECT: simplified process of fabrication of composite items, reduced labour input and production cost. ^ 2 dwg, 3 ex |
