Heat treatments of Inconel 718 nickel-based superalloy: A Review
Heat treatments are vital in obtaining suitable microstructural features leading to excellent high-temperature properties in Inconel 718 nickel-based superalloy. In this review article, the effects of various alloying elements of Inconel 718 like Fe, Cr, Al, Ti, Nb, Mo, Co, B, and C, and the relevant phases formed are discussed in context to the various heat treatments applied to the alloy. Heat treatments such as homogenization and age hardening applied to nickel-based superalloys in general and also specifically to Inconel 718 are reviewed in detail with respect to the processing routes employed, i.e., casting, wrought metallurgy, powder metallurgy and additive manufacturing. Some of the simulation techniques like the Scheil module in Thermo-Calc and DICTRA which are used for predicting the homogenization time and temperature are also discussed. The metallurgical aspects of nickel-based superalloys deal with their composition and property relationships, microstructure evolution, and various strengthening phases formed during heat treatments. The various precipitate phases of Inconel 718 i.e., γ′, γ′′ and δ formed during the processing and heat treatments, and their contribution to the enhancement of high temperature and room temperature mechanical properties are also elucidated in detail. The effect of precipitate volume fraction, morphology, and size on the enhancement of high-temperature and room-temperature mechanical properties is reviewed in particular as per recently published reports in this field.
期刊介绍：
Metals and Materials International publishes original papers and occasional critical reviews on all aspects of research and technology in materials engineering: physical metallurgy, materials science, and processing of metals and other materials. Emphasis is placed on those aspects of the science of materials that are concerned with the relationships among the processing, structure and properties (mechanical, chemical, electrical, electrochemical, magnetic and optical) of materials. Aspects of processing include the melting, casting, and fabrication with the thermodynamics, kinetics and modeling.
