The effects of alloying methods and melting process parameters on the composition uniformity of Ti-662 titanium alloy ingots were compared and analyzed by using different medium alloys and small particle sponge titanium as raw materials. The results show that the original distribution uniformity of the elements in the consumable electrode has a great influence on the uniformity of the chemical composition in different parts of the ingot for vacuum consumable arc melting,more uniform chemical composition can be obtained by adding multi-element medium alloys than by adding pure metals and binary alloys, increasing the melting times is beneficial to the composition uniformity at the top and the bottom of the ingot. By means of adding Cu and binary alloy, Ti-662 titanium alloy ingots with good uniformity of chemical composition can be obtained after three times argon-filled vacuum consumable melting,which can meet the needs of industrial production.It is necessary to develop individual multi-element medium alloys for alloys with high metallurgical requirements.
