Mechanical stabilization of martensite: comparison of Ni-Mn-Ga and Cu-Ni-Al shape memory single crystals
Original language description
Newly developed formalism, regarding 2H modulated Cu-Ni-Al system as non-magnetic equivalent of Ni-Mn-Ga 10M modulated martensite provides the way to compare behaviour of these two shape memory alloys. Here we study the mechanical stabilization by mechanical stress in the single crystals of Ni50.7Mn27.7Ga21.6 (at.%) and Ni46Mn24Ga22Co4Cu4 exhibiting 10M and non-modulated martensite structures, respectively, and for comparison in Cu69.4Ni3.4Al27.2 2H martensite. The resulting shift of reverse transformation temperature was almost 50 K in the Cu-Ni-Al 2H martensite and about 6 K in Ni-Mn-Ga non-modulated martensite. In contrast, the shift was <1 K in 10M Ni-Mn-Ga martensite. From the comparison it follows that the negligible stabilization in modulated 10M Ni-Mn-Ga can be due to its deep twinning hierarchy and very high mobility of twin boundaries.
