Bulk Defects in Pseudoelastically Cycled Cu-Zn-Al Single-Crystals
Centro Atómico Bariloche, Comisión Nacional de Energía Atómica, 8400 S.C. de Bariloche, Argentina
The pseudoelastic behavior, in Cu-Zn-Al alloys cycled between the bcc phase (β) and the 18R martensite structure was analyzed for tests performed within the range [-196 °C - 50 °C]. The role of the temperature, in these fatigue experiments, is pointed out by a different evolution of the σ-ε curves with cycling, which are related with changes in the nature and density of the defects formed in the bulk.
