Method for preparing block nanocrystalline alloy material

Abstract

The invention relates to nanocrystalline alloy, in particular to a method for preparing a block nanocrystalline alloy material through the cold pressure welding technology. A strip-shaped nanocrystalline alloy material is welded to be a block material in a cold mode based on the character that strip-shaped or sheet-shaped alloy materials are combined with a substrate material under huge pressure through acute plastic deformation cold welding. Due to the fact that obvious temperature rising does not exist in the cold pressure welding process, the finally obtained crystalline grains of the block material are not obvious different from original strips and are nanocrystalline.

Benefits of technology

This technology prevents crystal formation while making small particles for use in electronic devices or other applications that require precise placement on specific areas. It allows for efficient production without requiring expensive equipment like lasers or electron beams.

Problems solved by technology

This patented technical problem addressed in the patents relates to improving the quality and efficiency of producing high-strength metamaterial structures with small particles called microparticles due to their ability to enhance certain characteristics like tensile elongations and impact resistance compared to larger ones. These techniques include creation of tiny primary aggregated phases within these microparts, controlled heat treatments, use of specific alloys, control over shape changes, etc., while maintaining strong cohesive forces between them.
