摘要：
A direct evidence of the relation between {201¯}B19′ twinning in the deformed martensite and {114}B2 twinning in the TiNi alloys' parent phase after reverse transformation is demonstrated by conventional and high resolution electron microscopies. There is the continuity of K1 planes between the two twinnings. Such that the {201¯}B19′ twinning is retained after the {4¯11}B2 twinning as a complement of reverse transformation. The validity of the results is based on the orientation relationship between martensite and parent phases and the magnitude of twinning shear for both the twinnings.
