In this study, the mechanical behaviour of the GlidCop (R) AL-15, an oxide dispersion-strengthened (ODS) copper, is investigated. As the extrusion process leads to a morphological and crystallographic texture, specimens are loaded in a parallel or transverse direction to the extrusion direction. %26lt;br%26gt;Higher monotonic mechanical strength is observed when the loading axis is parallel to the extrusion direction. Under cyclic loading, the material is more prone to cyclic hardening-softening behaviour and exhibits higher fatigue resistance in the extrusion direction than in the transverse one.
