Fs-85 Niobium Alloy

Fs-85 Niobium Alloy

Purpose of FS-85 The structural element of the space shuttle orbital operating system engine is the niobium alloy FS-85 (Nb-28Ta-10W-1Zr ).

Light bulbs, rocket engines, and nuclear reactors are just a few of the high-temperature devices that use niobium alloys. Due to the special physical and chemical properties of these alloys, niobium alloys are often required to meet the requirements of specific applications. Compared to other refractory metals, niobium alloys have low density and are highly ductile even at low temperatures. Most niobium alloys have excellent corrosion resistance in acid and alkali liquid metals; however, without a protective layer, oxidation resistance at high temperatures is often catastrophic.

General description of commercial superalloys. The special properties of these alloys require unusual processing techniques and machinery. The important physical properties of these alloys are explored depending on certain uses. The requirements and design constraints of these applications provide useful insights for those working to create alternative high-temperature materials.
