Show Abstract
Recently, a novel stress-induced phase transformation in an initial 〈100〉/{100} B2-CuZr nanowire has been reported for the first time [ Sutrakar and Mahapatra, Mater. Lett. 63, 1289 (2009) ]. Following this, a martenisitic phase transformation in Cu–Zr nanowire was shown [ Cheng et al., Appl. Phys. Lett. 95, 021911 (2009) ] using the same idea [Sutrakar and Mahapatra, Mater. Lett. 63, 1289 (2009) ]. The pseudoelastic recovery of the bct phase of Cu–Zr by unloading has also been shown [ Cheng et al., Appl. Phys. Lett. 95, 021911 (2009) ]. They also tested the epitaxial bain path [ Alippi et al., Phys. Rev. Lett. 78, 3892 (1997) ] and reported that the bct phase in the nanowire is metastable, whereas the bulk counterpart is unstable. This aspect is re-examined in this comment with corrected results.
