Colour-coded IPF maps of Moss phase in the alloy obtained when looking on the specimen surfaces after short and longer creep exposure at 1500 °C and 137 MPa. The orientation distributions of grains are shown in a view direction parallel to the tensile axis. (a) Short creep exposure (2.9%, 4.3 h), showing a large connected Moss region with similar orientations. (b) Longer creep exposure (72%, 44 h) obtained at the same magnification as Fig. 8(a). (c) The -- standard triangle for cubic structures showing colour-coded crystallographic orientations. (d) Longer creep exposure, the same as Fig. 8(b), showing large connected Moss regions having very small grains with high and low angle grain boundaries. (e) and (f) Inverse pole figures of Moss phase corresponding to Fig. 8(a,b), respectively.
