Direct evidence of correlation between {2 0 1̄} B19 ′ and {1 1 4} B2 deformation twins in Ti–Ni shape memory alloy

The correlation between {2 0 1 ̄ } B19 ′ twinning in the deformed martensite and {1 1 4} B2 twinning in the reverse transformed parent phase in the Ti–Ni shape memory alloy is directly demonstrated by in situ heating conventional transmission electron microscopy (CTEM) and high resolution electron m...

Description
Summary:The correlation between {2 0 1 ̄ } B19 ′ twinning in the deformed martensite and {1 1 4} B2 twinning in the reverse transformed parent phase in the Ti–Ni shape memory alloy is directly demonstrated by in situ heating conventional transmission electron microscopy (CTEM) and high resolution electron microscopy (HREM) observations.
