“…Crystallization kinetics and microstructure of the as-spun Ti 50 Ni 25 Cu 25 ribbon has been reported earlier [2,7,8]. Previous investigations, where the samples were mostly annealed by CTA, show that annealing at a temperature higher than 450 • C is necessary to obtain fully crystallized material [2,8,9]. In the present study, the initially amorphous Ti 50 Ni 25 Cu 25 ribbon was found to be fully crystallized at 400 • C for only 30 s under RTA.…”

An automated method has been developed to characterize the type and spatial distribution of twinning in crystal orientation maps from synchrotron X-ray Laue microdiffraction results. The method relies on a look-up table approach. Taking into account the twin axis and twin plane for plausible rotation and reflection twins, respectively, and the point group symmetry operations for a specific crystal, a look-up table listing crystal-specific rotation angle-axis pairs, which reveal the orientation relationship between the twin and the parent lattice, is generated. By comparing these theoretical twin-parent orientation relationships in the look-up table with the measured misorientations, twin boundaries are mapped automatically from Laue microdiffraction raster scans with thousands of data points. Taking advantage of the high orientation resolution of the Laue microdiffraction method, this automated approach is also applicable to differentiating twinning elements among multiple twinning modes in any crystal system.

“…1) suggest that b-Ti, cubic NiTi (Pm3m), orthogonal NiTi (Pmma) and monoclinic NiTi (P21/m) compose the eutectic regions. The high cooling rate favors the formation of the NiTi martensitic product phases (orthogonal and monoclinic) from the austenitic parent phase (cubic) [19,20]. He et al [5] reported nanometer-sized grains (2-5 nm) inside the eutectic, which is supported by the current XRD line broadening, Table 1.…”
