Abstract: The present study involved uniaxial cold compression of two samples – generically termed as samples A and B (see figure 1). Both had a microstructure of hcp (hexagonal closed packed)  grains with grain boundary and tri-junction bcc (body centered cubic) . The two structures, however, had distinct differences: (i)  grains in sample B were approximately 1.5 times larger than  grains in sample A and (ii) hardness of  in sample A was more than twice that of in sample B. (ii) was due to fine  precipitates present in the  phase of sample A. Plastic deformation, in these two samples, had clear differences in microstructural developments. These are summarized below: • Softer , i.e.  phase in sample B, had more fragmentation and stronger developments in GAM (grain average misorientation). Similarly, softer , i.e.  phase in sample A, had more lattice strain and GAM. Such trends can be justified from the expected patterns of strain partitioning – more strain partitioning being expe...
