英文摘要:

      Molybdenum alloys are widely used as a kind of high-temperature structural material and function material in many areas such as metallurgical industry, aerospace, nuclear industry. With the development of relevant technology, molybdenum alloys applied range increased. While, higher usability requirement to molybdenum alloys appeared. The technical requirement of oxygen content in molybdenum alloy has been presented clearly in non-ferrous metals industry, medical apparatus and instruments process industry. The domestic and overseas research status of low oxygen preparation technology of the TZM molybdenum alloy, and the source of oxygen from the TZM molybdenum alloy are introduced. The major factor lead to oxidation in the processing of molybdenum preparation, oxygen content change and the effect of material thickness on oxygen content are discussed.The key technologies on low content molybdenum alloy preparation are summarized. Base on above analysis, additional comments about low oxygen content molybdenum preparation technology which did not involve in previous study and need improving are introduced. And its development prospect is put forward.
