| High mobility of a/c twin boundaries in 10M martensite of Ni-Mn-Ga is a unique phenomenon which can be used in various applications, e.g. actuation. The reason for the phenomenon may be the complex twinning system. This work is the first study of the interaction between monoclinic twinning and type II single twin boundary. We show at the level of optical microscopy that monoclinic twins crossing type II twin boundary are compatible enough to occur no or minor changes after type II twin boundary passage. |
