Abstract: The present disclosure provides a pulse current assisted uncanned rolling method for titanium-TiAl composite plates, including the following specific steps: 1. preparing titanium alloy sheets; 2. preparing TiAl alloy sheets; 3. uncanned lay-up; 4. pulse current assisted hot-rolling; 5. separation and subsequent processing, thus getting the titanium-TiAl composite plates. The composite plates are of good quality on the surface without oxide layer shedding, no cracks at the edges and the ends, with uniform and fine microstructures, good bonding interface and excellent mechanical properties.
