Deformation twinning with different twin-boundary mobility in 2H martensite in Cu-Ni-Al shape memory alloy

boundary is a coherent coplanar mirror plane with the smallest twinning shear. The Type II twin boundary is also a coherent strain-free interface. The high index rational approximation of Type II...

Reactions of slip dislocations with twin boundary in Fe-Si bicrystals

In situ TEM straining experiments on Fe-5.5 at.%Si were used to study the transfer of slip across a coherent twin boundary. Three different reactions of dislocations were observed in dependence on specimen orientation....

Real-time atomic-resolution observation of coherent twin boundary migration in CrN

Although coherent twin boundary (CTB) migration in fcc metals has been widely microscopy, we report two different twin boundary defect (TD) nucleation and CTB migration modes at the CTB/ITB (incoherent

Waves in spatio-spectral and -temporal coherence of evolving ultra-intense twin beams

Waves in the spatio-spectral and -temporal coherence of evolving ultra-intense twin beams are predicted: Twin beams with low intensities attain maximal coherence coherence wave. Rotationally-symmetric ...

Coherence and mode decomposition of weak twin beams

. Spatial and spectral coherence of weak twin beams is described by auto-and cross-correlation functions. Relation between the numbers of modes and coherence is discussed.Properties of weak spatio-spectral twin bea...

Waves in intensity coherence of evolving intense twin beams

their generation dominantly determine the properties of twin beams. They are also responsible for the waves in intensity coherence observed in the wave-vector space of a twin beam to develop at certain twin-beam i...
