| 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... |
