[0040] The present invention also provides a preparation method of the zirconium-containing TB10 titanium alloy, comprising the following steps:
[0041] Melting the alloy raw material according to the composition ratio of the zirconium-containing TB10 titanium alloy to obtain an alloy ingot;
[0042] performing solid solution treatment on the alloy ingot to obtain a solid solution alloy;
[0043] The solid solution alloy is annealed to obtain a zirconium-containing TB10 titanium alloy.
[0044] According to the composition distribution ratio of the zirconium-containing TB10 titanium alloy, the invention melts the alloy raw material to obtain the alloy ingot. In the present invention, there is no special limitation on the type of the alloy raw material, and the alloy raw material for smelting titanium alloy well known to those skilled in the art can be used. In the present invention, the alloy raw material preferably includes titanium, zirconium, molybdenum, vanadium, chromi...
