Abstract


  • In order to study the surface asperity flattening

    in a quasi-static cold uniaxial planar compression, the experimental

    results of atomic force microscope and electron

    backscattered diffraction have been employed in a ratedependent

    crystal plasticity model to analyze this process.

    The simulation results show a good agreement with the

    experimental results: in this quasi-static deformation process,

    lubrication can hinder the surface asperity flattening

    process even under very low deformation rate. However,

    due to the limitation of the model and some parameters, the

    simulation results cannot predict all the properties in detail

    such as S orientation {123} <634> and the maximum

    stress in sample compressed without lubrication. In addition,

    the experimental results show, with an increase in

    gauged reduction, the development of Taylor factor, and

    CSL boundaries show certain tendencies. Under the same

    gauged reduction, friction can increase the Taylor factor

    and E = 7.
