Role of stabilization heat treatment inducing γ′-γ″ co-precipitates and grain boundary η phase on tensile and creep behaviors of Inconel 706

Effect of microstructure on low cycle fatigue behavior of Inconel 706 at 650°C

“…Low-and high-magnification SEM micrographs of the F2 specimen in Figure 3 enrichment of Ni, Nb, and Ti and precipitate free zone around it, which matched to the nature of η precipitates in IN706. 44 While these η precipitates have been known to be not detrimental to mechanical properties of IN718, 9 no studies are available on elevated temperature LCF behavior of IN706. The microstructural features, including grain size and the area fraction of carbides, of each specimen are summarized in Table 4.…”

“…[5][6][7] IN706 has been developed to have improved fabricability, particularly machining, with similar mechanical properties to those of IN718. [8][9][10] Since the *Inconel alloy family was first developed in 1932, and its trademarks were registered by the International Nickel Company (INCO) in the United States. main application of IN706 is for very large commercial scale forgings used in power generation and chemical processing, over 15 tons of triple melted ingots by VIM (vacuum induction melting), ESR (electroslag remelting), and VAR (vacuum arc remelting) are often produced.…”

“…While IN718 has excellent mechanical and corrosion properties at room and elevated temperature up to 650°C, 1–4 conventional machining techniques of utilizing high‐strength tools may not be applicable due to its extremely tough nature and low machinability 5–7 . IN706 has been developed to have improved fabricability, particularly machining, with similar mechanical properties to those of IN718 8–10 . Since the main application of IN706 is for very large commercial scale forgings used in power generation and chemical processing, over 15 tons of triple melted ingots by VIM (vacuum induction melting), ESR (electroslag remelting), and VAR (vacuum arc remelting) are often produced.…”

The Studying of high-temperature deformation mechanism in a new light-weight high-strength HEAs from the view of internal fricition

“…Coble creep is generally believed to occur at medium temperature, which is typically defined as half the melting point of the alloy, resulting in low stress. [10] The second phase precipitation strength serves as a viable anti-creep technique and is extensively employed [11][12][13] . According to reports, Chen et al .…”
