The invention discloses a super-plasticity forming method for a GH4169 alloy ring part with a complex section. The method comprises the steps that GH4169 alloy is heated to the temperature of 1000+/-10 DEG C, after forge deformation with deflection of 40%-50%, the temperature is kept at 890 DEG C for 10 hours, then raised to 950 DEG C and kept for 3 hours, and a crystal GH4169 alloy blank is obtained; the GH4169 alloy blank is heated to forge temperature, and an alloy ring blank is obtained through upsetting, punching and levelling; the alloy ring blank is rapidly rolled and formed at the maximum feed speed of 1.7 mm/s at the temperature of 1060-1080 DEG C, and the GH4169 alloy ring part with the complex section is obtained. According to the method, the GH4169 alloy can be in a super-plasticity state in the forming process, so that the GH4169 alloy ring part with the complex section and both the performance and the size meeting requirements is obtained. The ring part is mainly taken as a connection ring, a bearing ring and the like to be widely applied to mechanized equipment in the industry areas such as aviation and aerospace.
