Abstract

The invention provides a metal wire pre-setting type friction stir processing method. The metal wire pre-setting type friction stir processing method comprises the following steps: providing a metal wire; providing base metal, opening a first mounting groove in the base metal and arranging the metal wire in the first mounting groove; and carrying out friction stir processing on the base metal andthe metal wire by utilizing friction stir equipment, wherein the metal wire comprises metal powder and tubular metal for surrounding the metal powder. The metal powder in the metal wire is surroundedand covered through the tubular metal, the metal powder is covered in the tubular metal in a stirring process and the contact area between the metal powder and air is effectively reduced, so that theoxidization rate of the metal powder is reduced and the processing quality of the base metal is improved.

Description

technical field [0001] The invention belongs to the technical field of friction stir processing technology, and more specifically relates to a preset metal wire type friction stir processing method. Background technique [0002] FSP (friction stir processing), that is, friction stir processing, is a kind of process that causes the base metal to undergo severe plastic deformation, mixing, and crushing through the strong stirring action of the stirring needle, and realizes the micro-densification, homogenization and refinement of the grains of the base material. processing technology. Usually, during the stirring process, different types of metal powders are correspondingly added to the base material, so that when the stirring needle acts on the base material, the metal powder is stirred at the same time, so that the crystal grains of the base material are further refined by the pinning effect. to obtain materials with better performance. [0003] In the prior art, the metal...
