Evolution of dislocations and a high pressure phase in a nanograin material under pressure and shear, obtained using a developed phase-field approach, reveals that shear-induced dislocations reduce the transformation pressure by a factor of 3-20 in comparison with hydrostatic conditions and suggests the nanoscale mechanism for explaining experimental phenomena.
