OSTI ID:10178795
The stress-induced phase transformation between C36 and C15 structures in Fe{sub 2}Zr is studied by electron microscopy. Nucleus of transformation is believed to be pre-existing C15 layers in C36 particles. Microstructural evidence for three mechanisms of growth of a new phase were found: Fault accumulation and rearrangement, moving of a individual partial dislocations between two phases, and the migration of microscopic ledges composed of a series of Shockley partials between C36 and C15. Plastic deformation by slip on non-basal planes of C36 caused by indentation is studied.
