The hot processing map was developed on the basis of experimental data using the principles of dynamic materials model, and the verification experiment of hot rolling process of Ti-Al clad plate was carried out based on the hot processing map. The results show that Ti-Al clad plate is a kind of positive strain rate sensitive material. The efficiency of power dissipation of 0.64~0.72 can be observed at 420~460 °C with strain rate of 1.6~6.3 s-1 in the hot processing map, and the process parameters of this region are suitable for the hot rolling of Ti-Al clad plate. After hot rolling, the interfaces of the Ti-Al clad plates are well bonded, and the plates have excellent mechanical property and good sheet metal forming property. The deformation mechanism of Ti-Al clad plate in the hot rolling process is as follows: the Al layer with low deformation resistance and fast flow can produce plastic deformation, and at the same time it can pull the Ti layer together to produce plastic deformation; in this process, the Al layer is hot deformation while the Ti layer is cold deformation."/>
