Abstract:Stock filling effect, microstructure and mechanical properties were analyzed for different forming processes based on TA15 alloy material using free forging, forging process and TA15 alloy bolt forming experiment. Experimental results show that the free forging can obtain TA15 alloy bolts with good filling effect and excellent mechanical properties at beginning forging temperature of 980 ℃, final forging temperature of 800 ℃ and die forging heating temperature of 955 ℃.
Key words: TA15 alloy; free forging; microstructure
