Outline Activities
The nanostructure analysis in advanced materials such as shape memory alloys, hydrogen permeation alloys is mainly performed by various electron microscopy techniques. The obtained results are fed back to the structure control in those materials. The basic researches on the phase transformation in metals and alloys are also performed.

Hiroshi Akamine, So Okumura, Sahar Farjami, Yasukazu Murakami, Minoru Nishida, Imaging of surface spin textures on bulk crystals by scanning electron microscopy, Scientific Reports, https://doi.org/10.1038/srep37265, 6, 2016.11, Direct observation of magnetic microstructures is vital for advancing spintronics and other technologies. Here we report a method for imaging surface domain structures on bulk samples by scanning electron microscopy (SEM). Complex magnetic domains, referred to as the maze state in CoPt/FePt alloys, were observed at a spatial resolution of less than 100 nm by using an in-lens annular detector. The method allows for imaging almost all the domain walls in the mazy structure, whereas the visualisation of the domain walls with the classical SEM method was limited. Our method provides a simple way to analyse surface domain structures in the bulk state that can be used in combination with SEM functions such as orientation or composition analysis. Thus, the method extends applications of SEM-based magnetic imaging, and is promising for resolving various problems at the forefront of fields including physics, magnetics, materials science, engineering, and chemistry..

Morphological and crystallographic studies of the variant selection rule, Philosophical Magazine, 10.1080/14786435.2012.669858, 92, in press, 2012.06, The self-accommodation morphologies of B190 martensite in Ti–Ni alloys
have been investigated by optical microscopy, scanning electron microscopy
(SEM) and transmission electron microscopy (TEM). Twelve pairs of
minimum units consisting of two habit plane variants (HPVs) with Vshaped
morphology connected to a f1 11gB190 type I variant accommodation
twin were observed. Three types of self-accommodation morphologies,
based on the V-shaped minimum unit, developed around one of the {111}B2
traces, which were triangular, rhombic and hexangular and consisted of
three, four and six HPVs, respectively. In addition, the variant selection
rule and the number of possible HPV combinations in each of these selfaccommodation morphologies are discussed..

Characteristic interface structures between habit plane variants, Philosophical Magazine, 10.1080/14786435.2012.669860, 92, in press, 2012.06, Four characteristic interface microstructures between habit plane variants
(HPVs) in the self-accommodation morphologies of B190 martensite in
Ti–Ni alloys have been investigated by scanning transmission electron
microscopy (STEM). The straight interface of a f1 11gB190 type I twin is
present at interface I. The relaxation of the transformation strain at
interface II is achieved by a volume reduction of the minor correspondence
variants (CVs) in the relevant habit plane variants (HPVs). The relaxation
of the transformation strain at interface III is mainly due to the formation
of a f1 11gB190 type I twin between the two major CVs. Subsequently, local
strain around the tips of the minor CVs perpendicular to the interface is
released by the formation of micro-twins with the h011iB190 type II and/or
f1 11gB190 type I relation. The major and minor CVs in each HPV are
alternately connected through fine variants with the f1 11gB190 type I twin
relation parallel to interface IV. The results are compared with macroscopic
observations and the predictions of PTMC analysis..

Analysis of habit plane variant clusters
by the geometrically nonlinear theory, Philosophical Magazine, 10.1080/14786435.2012.669860, 92, in press, 2012.06, Competition between the invariant plane (IP) condition at the habit plane,
the twin orientation relation (OR) and the kinematic compatibility (KC) at
the junction plane (JP) of self-accommodated B190 martensite in Ti–Ni was
investigated via the geometrically nonlinear theory to understand the habit
plane variant (HPV) clusters presented in Parts I and II of this work. As the
IP condition cannot be satisfied simultaneously with KC, an additional
rotation Q is necessary to form compatible JPs for all HPV pairs. The
rotation J necessary to form the exact twin OR between the major
correspondence variants (CVs) in each HPV was also examined. The
observed HPV cluster was not the cluster with the smallest Q but the one
satisfying Q¼J with a {1 11}B190 type I twin at JP. Both Q and J are crucial
to understanding the various HPV clusters in realistic transformations.
Finally, a scheme for the ideal HPV cluster composed of six HPVs is also
proposed..
