Abstract: A magnesium/titanium composite plate with large thickness ratios and a gradient heterothermal rolling bonding method are provided by the present disclosure, relating to the technical field of rolling bonding plates. The method includes following steps: assembling blanks according to a sequence of titanium strip, transition layer foil and magnesium alloy plate to obtain a composite blank; carrying out induction heating treatment on one side of the titanium strip of the composite blank, then rolling, and carrying out heat treatment on a composite plate blank after rolling to obtain the magnesium/titanium composite plate with large thickness ratios; and a thickness ratio of the magnesium alloy plate to the titanium strip is greater than or equal to 20:1.
