This study deals with the Inconel 625 (IN625) alloy reinforced micro-TiC particles processed by laser powder bed fusion. The microstructure and hardness in as-built solution-annealed states were investigated. microstructures of IN625 IN625/TiC primarily made up columnar grains along building direction. After solution annealing at 1150 °C for 2 h, consisted equiaxed due to recrystallization grai...

Inconel 625 (IN625) superalloys can be easily fabricated by the laser-based powder bed fusion (PBF-LB/M) process, allowing production of components with a high level design freedom. However, one main drawbacks PBF-LB/M process is control over thermally induced stresses and their mitigation. A standard approach to prevent distortion caused residual stress performing stress-relieving (SR) heat tr...

Additively manufactured multi-metal hybrid structures can be designed as functionally graded materials providing an optimized response at specific positions for particular applications. In this study, liquid dispersed metal powder bed fusion is used to synthesize a structure based on Inconel 625 (IN625) and stainless steel 316L (S316L) regions, built S316L base plate. Both alloys alternate seve...

The dissimilar combination of 2.25Cr-1Mo (P22) and modified 9Cr-1Mo (P91) obtained using Gas Tungsten Arc Welding (GTAW) process employing the Ni-based superalloy filler ERNiCr-3 (IN82) ERNiCrMo-3 (IN625) have been investigated for microstructure evolution mechanical properties. butt weld joint was produced single bevel groove geometry. structural integrity welded measured in respect tensile st...

Cobalt is the most used metal binder in hard metals since its extraordinary wetting, adhesion and mechanical properties. Nevertheless, it has been recognized genotoxic cancerogenic with higher toxicity combination WC. To substitute Co an alternative binder, interaction between WC must be taken into account. In this work, IN625 considered as a due to desirable of high-temperature strength corros...

Abstract In developing the Wire + Arc Additive Manufacturing (WAAM) process for manufacture of components used in high-speed flight environments, a selection suitable alloys was devised. Using material properties from literature sources, creep-resistant were down-selected based on requirement service high temperature, stress environment and need an alloy using WAAM process. Down-selected alloys...

The present state of melting techniques for IN7 18 and IN625 has well-defined limitations both in terms of the ingot structure and maximum ingot size which is fabricable by the various processes. Although there are methods already in industrial use which would extend both of these limits, since the alloys must be produced at a relatively low cost here are further limitations on the practical ma...
