説明
<p>The work hardening of aluminum alloys depends on the dislocation substructure in addition to the dislocation density. In this study, in-situ XRD measurements during tensile deformation were conducted on cold-rolled 1200 aluminum and change in the dislocation substructure was evaluated by analysis using Convolutional Multiple Whole Profile method. As a result, the dislocation cell structure was formed before tensile test and when the stress exceeded 32 MPa, the dislocation cell structure decomposed and the dislocation dispersion approached uniformly. It is considered that 32 MPa is a micro-yield stress at which the initial dislocations start to move. As the plastic deformation progressed, dislocation arrangements parameter decreased and finally became 0.5, it is considered that the dislocation cell structure was formed again.</p>
