Crystallography of martensitic transformation in TiNi single crystals

Physical metallurgy of Ti–Ni-based shape memory alloys

“…under stress observed with respect to Fig. 24 also supports the mechanism (strictly speaking, the Schmid factors were the largest or the second largest in this case [131].). As the other checkpoint, we may compare the amount of the recoverable strain with experiment.…”

“…The first report on the habit plane measured by two-surface analysis on Ti-Ni single crystals was made by Saburi et al [138] and Miyazaki et al [139]. More complete work on the crystallography of the transformation in a Ti-Ni alloy was done by Matsumoto et al [131], who measured habit plane, orientation relationship and shape strain simultaneously on single crystals and made critical comparison with the theory. The results of their calculations are essentially the same as those by Knowles and Smith.…”

Infinitesimal approach to the crystallography of martensitic transformation: application to Ni-Ti

“…Here, the paper by Knowles and Smith [11] and that by Matsumoto, Miyazaki, Otsuka and Tamura [12], the calculations based on the phenomenological theory, are referred to. The rational interface plane, (1, 1, 0) for ƒ ϭ 0.2710 and (1, 1, Ϫ1) for ƒ ϭ 0.3102, were also reported by both groups.…”

Structure of the near-surface layer of NiTi on the meso- and microscale levels after ion-beam surface treatment

“…The analysis suggests that the crystallographic transition 2 19 can be described by operations of rotation of the basis 2; matrices are used to perform rotation and shear for monoclinic distortion of unit cell. To provide for one-to-one correspondence of the 2 and 19 structures in terms of crystallography, we applied the orientation relations obtained by the workers in [5]. Matrices were calculated to perform rotations for each out of twelve possible variants of martensite 19 , which are equivalent in terms of crystallography.…”
