Zusammenfassung:	The invention provides a preparation method of a TA15-1 thin plate, which comprises the following steps: sequentially carrying out vacuum consumable smelting to obtain a cast ingot, forging cogging, rough rolling cogging, finish rolling cogging and cold rolling to obtain the TA15-1 thin plate. The method is characterized in that through reasonable composition proportion, forging cogging and rough rolling cogging are carried out at the temperature slightly higher than the phase transformation point; the temperature and the deformation rate start to be adjusted in the finish rolling (hot rolling) stage, the structure property control stage is started, and the control key points comprise the heating temperature, the finish rolling temperature, the deformation rate and the like; the deformation rate of the cold rolling procedure and the rolling process needs to be designed in the cold rolling stage, so that the material tissue is fully broken but does not exceed the deformation limit; by adjusting the heat treatm
