Abstract

The intermetallic precipitation process used for strengthening the nickel-base superalloy Inconel 718 was studied using nanometer resolution analytical electron microscopy. A modified IN718 alloy specimen was fabricated and subjected to heat treatment before its morphology, composition and structure were analyzed through microscopic examinations. Results indicate a frequent association between the metastable and tetragonal precipitates in the specimen. This enhances the microstructural stability of the modified alloy at high temperatures.
