Abstract

<abstract> <title> <x xml:space="preserve">Abstract</x> </title> <p>In this work, twinning systems of tensile deformed commercial purity titanium were studied using the electron backscatter diffraction technique and Schmid factor analysis. The dependence of twinning on the matrix orientation was determined by the distribution map of the Schmid factor. The results showed that both &lt;inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="mst-29-06-754-e02.tif"/&gt; &lt;inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="mst-29-06-754-e03.tif"/&gt; compressive twins and &lt;inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="mst-29-06-754-e04.tif"/&gt; &lt;inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="mst-29-06-754-e05.tif"/&gt; tensile twins are dependent on the matrix orientation. Twins were activated in the grains with large values of twinning Schmid factor. The critical shear stress and Schmid factor of a grain determined the activation of a particular twinning system.</p> </abstract>
