Furthermore, the dual effect of compressive stress on SFTs is verified in terms of energy. It is revealed that compressive stress can reduce the transformation barrier from vacancy platelets to SFTs, thereby promoting the formation of SFTs. Additionally, the transformation from SFT to Frank dislocation loop induced by compressive stress is further investigated in terms of enthalpy.
