Abstract:
Some modern sintering technologies such as microwave sintering, some advanced high purity technologies such as electron beam melting, some near net shape forming such as 3D printing and some oxidation resistant technologies such as coating were introduced, including the base theory, superiority, research status and primary application in refractory metals. It is the trend to higher purity, higher oxidation resistance and net shaped forming for refractory metals’ manufacturing. Some important questions should be solved at the first for advanced manufacturing technology application in refractory metals. It would need a lot of experiments base status, and need to enhance the single crystal’s purity, variety and size. In order to instead of traditional forged pieces, it is necessary to resolve how to control the internal structure, defect and mechanical property of the near net shape forming products.
