【 摘 要 】

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. 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.
