在第九届国际真空会议上,不少科学家认为:超高真空用的新型铝合金材料的研制是现代真空技术所取得的重要进展之一。铝合金材料之所以引起人们的重视,是因为它具有重量轻、表面清洗容易、机械加工方便、价格低廉、无铁磁性、热传导率高、出气率低等优点。铝合金材料在真空容器中的应用是继不锈钢真空容器出现之后的一件大事。本文将根据有一定代表性的资料向大家介绍一下关于这类铝合金材料的真空性能方面的研究结果。所介 At the Ninth International Vacuum Conference, many scientists believe that the development of new aluminum alloy materials for ultrahigh vacuum is one of the important advances made in modern vacuum technology. Aluminum alloy material has attracted people’s attention because it has the advantages of light weight, easy surface cleaning, easy machining, low price, no ferromagnetism, high thermal conductivity and low outgassing rate. The use of aluminum in vacuum vessels is a major event following the appearance of stainless steel vacuum vessels. This article will be based on a representative of the information to tell you about the vacuum properties of such aluminum alloy research results. By the introduction
