Some embodiments of the disclosure provide a toughened TiAl-based alloy sheet with periodically misaligned through-hole titanium alloy layers sequentially stacked together. A through structure is formed in the misaligned through-hole titanium alloy layer. Two openings of the through structure are respectively located on upper and lower surfaces of the titanium alloy layer. The misaligned opening position of the through structure is at a center position of a quadrangle formed by every four through holes in adjacent titanium alloy layers. The through structure is filled with a TiAl-based alloy. The TiAl-based alloy layers on adjacent sides of the titanium alloy layer are connected through the TiAl-based alloy in the through structure. The TiAl-based alloy layer is connected to the titanium alloy layer through a TiAl interface layer. The TiAl-based alloy and the titanium alloy in the through structure are connected through a TiAl interface layer.
