## Description

- description: 'In order to apply conventional forming processes at the micro scale,
    the size effects caused by material properties and frictional effects must be
    taken into account. In this research, the effects of tool surface properties such
    as punch surface grooves on microextrudability, assessed using extrusion force,
    shape of the extrusion, and Vickers hardness, were investigated using an AA6063
    billet. Microscale grooves of 5 to 10 µm were fabricated on the punch surface.
    The extrusion force increased rapidly as the stroke progressed for all the grooves.
    Comparing the product geometries showed that, the smaller the groove size, the
    lower the adhesion and the longer the backward extrusion length. The results of
    material analysis using EBSD showed that a 5 µm groove depth punch improved the
    material flowability and uniformly introduced more strain. On the other hand,
    material flowability was reduced and strain was applied nonuniformly when a mirror-finish
    tool was used. Therefore, the tribology between the tool and the material was
    controlled by changing the surface properties of the punch to improve formability. '
