摘要： Process for producing a ductile, high strength, oxide dispersion hardened sintered alloy based on a metal having a high melting point. In the past, oxide dispersion has played only a minor role in comparison with other known processes for increasing strength. The process disclosed permits cost-effective production of metallic materials which possess a strength hitherto unttainable by oxide dispersion and a higher ductility than prior art materials. As a result, the metallic and nonmetallic foreign components in the sintered alloy can be restricted to the relatively small quantities of dispersoids and any dissolved residual oxygen. The process consists in an annealing treatment and calls for a specific choice of basis metal and suitable oxide dispersoid. The materials so obtained are used mainly where metallic components possessing high strength and ductility together with a minimal concentration of foreign elements are required, for example in human medicine where stringent requirements concerning corrosion resistance and biocompatibility apply or in nuclear technology to prevent undesirabble particle reactions.
