ADDITIONAL STRENGTENING OF SUPERALLOY NIMONIC Superalloy Nimonic 80A is the alloy from series NIMONIC nickel-base superalloys that contain 20% of chromium . It is intended for use at elevated and high temperatures at which the creep process occurs significantly. The primary strengthening mechanism of this superalloy is based on precipitation
Abstract Nimonic 80A superalloy with high-temperature strength and high-corrosion resistance is used in jet engines for aircraft, gas turbines for power plant and marine diesel engines, etc. To set favorable hot forging conditions of Nimonic 80A, various mechanical tests such as the hot compression test and the micro-Vickers hardness test have been performed under various test conditions.
Mechanical micro-drilling of nimonic 80A superalloy using Micro-drilling experiences an early tool damage which is a major drawback for nickel-based superalloy. This paper examines the wear condition on the micro-tool cutting edge, surface roughness of machined holes, and hole diameter analysis in micro-drilling of Nimonic 80A, using two types of micro-drills (uncoated and TiAlN coated) with 0.79 mm diameter.
Microstructural evolution of Nimonic 80a during hot Nimonic 80a is a wrought, age-hardenable nickel-based superalloy, strengthened by the addition of titanium, aluminium and carbon.
Nimonic 105 focuses on both superalloy mechanisms and by doing so is able to handle temperatures up to 950°C! Nimonic C263. Ni, 20% Cr, 20% Co, 6% Mo, 1.9-2.4% Ti. Nimonic C263 with essentially no Al. This means as a superalloy it relies on solely on

Performance analysis of coated carbide tool in turning of Aug 01, 2020 · Nimonic 80A is a type of superalloy which maintains its yield strength even at 900 °C and can be utilized safely in high temperature applications.
This study investigates the effect of heat treatment on the mechanical properties of a forged Nibased superalloy called Nimonic 80A. Nimonic 80A ingot samples were fabricated by vacuum spray casting to achieve a fine and homogenized microstructure. The ingot samples were subsequently hot-forged with the diameter of 220 mm at 1373 K. From the center to the surface of the forged Nimonic 80A, its
