Electromagnetic impact strengthening method for titanium alloy

The invention relates to an electromagnetic impact strengthening method for a titanium alloy. The electromagnetic impact strengthening method comprises the following steps: step 1, sampling on a to-be-treated titanium alloy material, and observing the orientation of a primary alpha phase of the to-be-treated titanium alloy material through a metallographic microscope; step 2, recording volume percentage of the primary alpha phase of a material metallographic phase and a dimension distribution condition of the primary alpha phase of the material metallographic phase, determining electromagneticimpact treatment parameters according to content of the primary alpha phase of the material metallographic phase and the dimension distribution condition of the primary alpha phase; step 3, clampingthe to-be-treated titanium alloy material onto electric pulse treatment equipment, introducing pulse current in an extending direction of the primary alpha phase of the titanium alloy material under protection of inert gas, pe
