COMPOSITE METALLIC ARTICLE AND THE METHOD OF ITS MANUFACTURE Russian patent published in 2008 - IPC B32B7/04 B32B15/02 B23D61/00 

FIELD: metallurgy industry; other industries; methods of production of the composite metallic articles made out of different metals.

SUBSTANCE: the invention may be used at manufacture of the composite metallic articles made out of two different metals, in particular, the saw blades. The metal base has the opposite surfaces, on each of which there is at least one lengthwise located recess. The elongated metallic component manufactured out of the more hard metal is introduced into each recess of the metal base for formation of the composite assemblage. The composite assemblage is heated under pressure with the purpose to press the adjacent surfaces together to produce the bound article. At that they restrain the lateral spread of the composite assemblage at the expense of application of the lateral binding pressure. The horizontal and vertical rolls of the stand used for manufacture of the composite metal article are disposed with the capability of limitation of the lateral spread of the composite assemblage. The invention ensures production of the composite article with the high strength of the binding between the forming it metals with the minimal damage of the material in the field of the binding.

EFFECT: the invention ensures production of the composite article with the high strength of the binding between the forming it metals with the minimal damage of the material in the field of the binding.
