Influence of fiber alignment on creep in directionally solidified NiAl-10Mo in-situ composites

► Directionally solidified NiAl-Mo eutectic yield Mo-fiber reinforced NiAl. ► Depending on growth rate well-aligned or cellular microstructures are achieved. ► Creep testing at 900 °C shows large differences in creep strength. ► Creep model is applied to describe difference of cellular and well-aligned samples.
