Abstract

<abstract abstract-type="graphical"> <title> <x xml:space="preserve">Abstract</x> </title> <p>The three‐dimensional morphology of topologically close packed phases (TCP) in an experimental 6 wt% rhenium‐containing superalloy is examined with focused ion beam tomography and compared to the existing knowledge gained with classical microscopy of two‐dimensional cross‐sections. The results show completely new insights compared to investigation of cross‐sections. With the new technique, three different types of TCP‐phase morphologies and the orientation of their growth planes could be identified: complex shaped plates, needles, and laths. In the classical cross‐section, they all appear to be needles. A part of the needles is penetrating the plate‐like precipitates. Possible conclusions on the growth mechanism are discussed. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg4sr4j05g" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
