Medical devices, such as endoprostheses, and methods of making the devices are disclosed. The endoprostheses comprise a tubular member capable of maintaining patency of a bodily vessel. The tubular member includes a mixture of at least two compositions, where the presence of the second composition gives the mixture a greater hardness than that of the first composition alone. The first composition includes less than about 25 weight percent chromium, less than about 7 weight percent molybdenum, from about 10 to about 35 weight percent nickel, and iron. The second composition is different from the first and is present from about 0.1 weight percent to about 5 weight percent of the mixture.

Medical devices including hardened alloys

A precipitation hardenable nickel base alloy that provides a novel combination of elevated temperature strength, ductility, and reduced notch sensitivity at temperatures up to about 1300&#xb0; F. is described. The alloy contains, in weight percent, about the balance being nickel and usual impurities. An article made from the alloy and a method of making the alloy are also disclosed.

Age-hardenable, nickel-base superalloy with improved notch ductility

An age hardenable nickel base chromium, molybdenum, alloy as well as intermediate products and articles made therefrom are disclosed which, in the solution treated and age hardened condition, have a 0.2% yield strength greater than 100 ksi combined with resistance to pitting and crevice corrosion and to stress corrosion cracking in chloride and sulfide environments at elevated temperatures up to about 500.degree. F. without requiring working below the recrystallization temperature of the alloy. Broad and preferred ranges are disclosed as follows:

Corrosion resistant age hardenable nickel-base alloy
