What is NIMONIC made of?
Nimonic alloys are primarily composed of nickel and chromium. These alloys are known for their high-temperature low-creep and high performance. Additives like aluminium, carbon and titanium are infused into the alloy.
What is NIMONIC 80A?
NIMONIC® alloy 80A (UNS N07080/W. Nr. 2.4952 & 2.4631) is a wrought, age-hardenable nickel-chromium alloy, strengthened by additions of titanium, aluminum and carbon, developed for service at temperatures up to 815°C (1500°F). It is produced by high-frequency melting and casting in air for forms to be extruded.

Are NIMONIC alloys single crystal?
Ni-based alloys are roughly classified into two grades of cast-type single-crystal superalloys for blade applications and wrought-type alloys for turbine disc applications (Reed, 2006).
What are superalloys used for?
Superalloys are an important group of high-temperature materials used in the hottest sections of jet and rocket engines where temperatures reach 1200–1400 °C. Superalloys are based on nickel, cobalt or iron with large additions of alloying elements to provide strength, toughness and durability at high temperature.
Why are nickel superalloys used?
Nickel based alloys and superalloys are widely used where good corrosion resistance and high-temperature performance are required.
What is gamma nickel?
Gamma ( ): The continuous matrix (called gamma) is an face-centered-cubic (fcc) nickel-based austenitic phase that usually contains a high percentage of solid-solution elements such as Co, Cr, Mo, and W.
Are superalloys brittle?
Precipitates can be classified as geometrically close-packed (GCP), topologically close-packed (TCP), or carbides. GCP phases are usually good for mechanical properties, but TCP phases are often deleterious. Because TCP phases are not truly close packed, they have few slip systems and are very brittle.
How are nickel based superalloys made?
Many superalloys are produced using a two-phase heat treatment that creates a dispersion of cuboidal γ’ particles known as the primary phase, with a fine dispersion between these known as secondary γ’. In order to improve the oxidation resistance of these alloys, Al, Cr, B, and Y are added.
What is so special about superalloys?
Superalloys are a group of nickel, iron–nickel and cobalt alloys used in jet engines. These metals have excellent heat resistant properties and retain their stiffness, strength, toughness and dimensional stability at temperatures much higher than the other aerospace structural materials.
What is the composition of Nimonic 75?
Nimonic 75 (UNS N06075) is a 80/20 nickel-chromium alloy with controlled additions of titanium and carbon. Nimonic 75 has good mechanical properties and oxidation resistance at high temperatures.
What is the temperature of Nimonic alloy 75?
NIMONIC alloy 75 can be hot forged at temperatures in the range of 982-1204°C (1800-2200°F). Cold working may be done on the alloy.
What is alloy 75 made of?
Alloy 75 (UNS N06075, Nimonic 75) is a 80/20 nickel-chromium alloy with controlled additions of titanium and carbon.
How do you Weld Nimonic 75?
NIMONIC alloy 75 can be welded using common techniques, using a matching filler metal. A prerequisite for welding is that the metal should be annealed. Manual metal arc welding, tungsten inert gas welding and metal inert gas welding suit the alloy.
