    <title language="eng">On the nature of gamma' phase cutting and its effect on high temperature and low stress creep anisotropy of Ni-base single crystal superalloys</title>
    <abstract language="eng">The creep anisotropy of the single crystal superalloy LEK 94 deformed in tension along [0 0 1] and [1 1 0] directions at 1293 K and 160 MPa was investigated. Elementary microstructural processes which are responsible for a higher increase in creep rates with strain during [1 1 0] as compared to [0 0 1] tensile loading were identified. [1 1 0] tensile creep is associated with a higher number of γ' phase cutting events, where two dislocations with equal Burgers vectors of type &lt;1 1 0&gt; jointly shear the γ' phase. The resulting &lt;2 2 0&gt;-type superdislocation can move by glide. In contrast, during [0 0 1] tensile loading, two dislocations with different &lt;1 1 0&gt;-type Burgers vectors must combine for γ' phase cutting. The resulting &lt;2 0 0&gt;-type superdislocations can only move by a combination of glide and climb. The evolution of dislocation networks during creep determines the nature of the γ' phase cutting events. The higher [1 1 0] creep rates at strains exceeding 2% result from a combination of a higher number of cutting events (density of mobile dislocations in γ') and a higher superdislocation mobility (&lt;2 2 0&gt; glide) in the γ' phase.</abstract>
