| Abstract: | Recent advances in micromechanisms of multiaxial fatigue under nonproportional loading are presented in the paper. The theory of additional hardening and its affecting factors are mainly discussed from the perspective of microstructure deformation. Finally, the ideas about the research of multiaxial fatigue micromechanisms under nonproportional loading are proposed. |

| Keywords: | multiaxial fatigue micromechanisms nonproportional loading additional hardening dislocation structure |
