... symmetries of the parent and product phases obey no group-subgroup relation [1; 2; 3]. RMTs include most famously, for simple Bravais lattices, the bcc-fcc structural transition taking place in many metals, alloys, and minerals, of great importance in science and technology [4]. We focus on the case of RMTs...
