Precipitation of the stable phases in Cu-Al-Ni shape memory alloys
- Univ. del Pais Vasco, Bilbao (Spain)
The Cu-Al-Ni based shape memory alloys are developed as an alternative to the classically Cu-Zn-Al and Ti-Ni used alloys. In this work the authors study the precipitation kinetics of the {gamma}{sub 1} pro-eutectoid phase and the {gamma}{sub 1} + {alpha} eutectoid decomposition between 400 C and 482 C. It should be noted that the {gamma}{sub 1} phase has been generally named {gamma}{sub 2}, although the authors will denominate that phase {gamma}{sub 1} according with the last reviews. The study of these precipitation kinetics will allow them to obtain the values of the microstructural parameters that control these processes and to estimate the stability of the {beta} phase at the using temperatures of these alloys.
