A New Low-Cost, Short-Flow, and Clean Preparation Process for Ti6Al4V Alloys

Ti6Al4VTi6Al4V alloy has many advantages such as high specific strength, good corrosionCorrosion resistance and biocompatibilityBiocompatibility, and is the most widely used titaniumTitanium alloy. At present, the industrial production of titaniumTitanium must use titaniumTitanium sponge (Kroll method) as raw materialMaterials, and the production cycle is long, high cost, cannot meet the requirements of the development of circular economy and environmental protection, which greatly limits the large-scale application of titaniumTitanium. We have designed and developed the “high-performance titaniumTitanium/titaniumTitanium alloy thermoelectric coupling low-cost short-flow preparationPreparation of a series of new processProcess system”. We have designed and developed a new method to prepare Ti6Al4VTi6Al4V alloy powder by self-propagatingSelf-propagating multistage reduction and one-step in-situIn-situ reduction using Ti6Al4VTi6Al4V alloy as the representative titaniumTitanium alloy. The method has completed semi-industrial tests and established the world's first demonstration production line for the low-cost, short-flow, clean production of Ti6Al4VTi6Al4V powder and TiTi powder by this method, which can reduce the cost of titaniumTitanium production by more than 30%, and is expected to boost the further development of the titaniumTitanium and titaniumTitanium alloy industry.
