Quantities of niobium are used in nickel-, cobalt-, and iron-based superalloys in proportions as great as 6.5% for such applications as jet engine components, gas turbines, rocket subassemblies, turbo charger systems, heat resisting, and combustion equipment. Niobium precipitates a hardening γ''-phase within the grain structure of the superalloy.

When used as a micro-alloying element, the metal becomes niobium nitride and niobium carbide. The resulting niobium alloys are used in various applications from automobiles to pipelines. In the manufacture of super-alloys wherein niobium is mixed with cobalt, nickel, and iron that, in turn, are used in high-tech applications.

Cobalt is a chemical element with the symbol Co and atomic number 27. Like nickel, cobalt is found in the Earth's crust only in chemically combined form, save for small deposits found in alloys of natural meteoric iron.The free element, produced by reductive smelting, is a hard, lustrous, silver-gray metal.. Cobalt-based blue pigments (cobalt blue) have been used since ancient times for ...

Cobalt (symbol: Co; atomic number: 27) is a naturally-occurring free element that, once subjected to reductive smelting, becomes a hard and lustrous metal with a silver-gray appearance. In its natural form, it can only be found in combination with other chemicals (i.e., chemically combined form) except for small deposits found in natural ...

However, such cobalt-iron-nickel-niobium-alloy only poorly satisfied the need for a high metal-glass-adhesive strength which bond strength constitutes a significant prerequisite for good sealability. A further disadvantage is that this alloy requires the presence of niobium which is a relatively expensive metal, whose melting point is nearly ...

The most important type of superalloy is the nickel-based material that contains a high concentration of chromium, iron, titanium, cobalt and other alloying elements. Nickel superalloys can operate for long periods of time at temperatures of 800–1000 °C, which makes them suitable for the hottest sections of gas turbine engines.

These results show that iron, cobalt and nickel diffuse abnormally fast in niobium whereas the latter displays no curvature (on an Arrhenius plot) in self-diffusion. Analysis of all available data for impurity diffusion in niobium shows that the solidus rule proposed by Roux and Vignes (1970) is completely quantitative as regards both ...

A nickel-base alloy containing correlated percentages of chromium, cobalt, tungsten, molybdenum, titanium, aluminum, carbon, tantalum, niobium, zirconium, hafnium, boron, yttrium and lanthanum displays excellent stress rupture strength at elevated temperatures together with good corrosion resistance in sulphur- and chloride-containing environments.

The Role of Niobium in Superalloys. Refractory elements are important alloying additions in both nickel-base and iron-nickel-base superalloys. They are responsible for the increased high-temperature mechanical properties present in current superalloy systems. In this article, we'll take a look at the role of niobium in superalloys.

Frequently, cobalt is associated with nickel because both elements have characteristic ingredients of meteoric iron. This solid ferro- magnetic silver-white element was known in ancient times for its compounds, but its discovery was credited to G.

The element Niobium was discovered by Charles Hatchett in year 1801 in United Kingdom. Niobium derived its name from from Niobe, daughter of king Tantalus from Greek mythology. The element Cobalt was discovered by Georg Brandt in year 1735 in Sweden. Cobalt derived its name derived its name from from the German word Kobold, meaning 'goblin'.
