    Micro Backward Extrusion

## Description

- description: To apply conventional forming processes to microscale processing, the
    influence of size effects caused by material properties and friction effects must
    be considered. In this study, the ef-fects of tool surface properties, such as
    punch surface texture, on micro-extrusion properties, such as extrusion force,
    product shape, and product microstructure, were investigated using AA6063 billets
    as test pieces. Millimeter-scale, microscale, and nanoscale textures were fabricated
    on the punch surfaces. The extrusion force increased rapidly as the stroke progressed
    for all punch tex-tures. In comparing the product shapes, the smaller the texture
    size, the lower was the adhesion and the longer the backward extrusion length.
    The results of material analysis using electron backscatter diffraction show that
    material flowability is improved, and more strain is uniformly applied when a
    nanoscale-textured punch is used. By contrast, when a mirror punch was used, material
    flowability decreased, and strain was applied non-uniformly. Therefore, by changing
    the surface properties of the punch, the tribology between the tool and material
    can be controlled, and formability improved.
