What is the main cause of formation of Laves phase?

Laves phases are intermetallic compounds that have a stoichiometry of AB2 and are formed when the atomic size ratio is between 1.05 and 1.67.

What is Laves phase in Inconel 718?

The Laves phase is about 1 μm in width and 10 μm in length, and there is no δ phase precipitated in the LDED sample. A large amount of δ phase precipitate in LDED Inconel 718 after aging treated at 890 °C for 12 h, as shown in Fig. 3(b).

What type of material is Inconel 718?

nickel chromium material
INCONEL® alloy 718 (UNS N07718/W.Nr. 2.4668) is a high-strength, corrosion-resistant nickel chromium material used at -423° to 1300°F.

What is the chemical composition of Inconel?

This superalloy is composed mainly of nickel (58% min.) followed by chromium, and molybdenum, niobium, iron, tantalum, cobalt, and trace amounts of manganese, silicon, aluminium, and titanium. Inconel 625 also commonly goes by the names: Haynes 625, Altemp 625, Nickelvac 625, and Nicrofer 6020.

What is the composition of Inconel 718?

Inconel 718 is a precipitation-hardenable nickel-chromium alloy containing also significant amounts of iron, niobium, and molybdenum along with lesser amounts of aluminum and titanium. It combines corrosion resistance and high strength with outstanding weldability including resistance to postweld cracking.
