Abstract: The effects of electroshocking treatment (EST) on microstructure evolution of dual-phase Ti were investigated by Molecular Dynamics (MD) simulation. From MD results, EST induced the sliding and rotating motion of atoms at grain boundaries, and promoted the interface shift and microregion phase transition. The thermal and athermal effects of EST were distinguished as well. The MD result of microregion phase transition was verified via in situ TEM experiment. All results revealed the effect mechanism of EST.
