Nickel Alloy GH2696
Nickel alloy GH2696 is a high-temperature alloy with molybdenum-niobium as the main reinforcing element, which is limited to a long-time service temperature of less than 650°C, but can reach an astonishing 750°C for short-time service. The yield, endurance, and creep strengths of this alloy are quite high, and it also has good high-temperature elastic properties, resistance to gas corrosion, and machining plasticity. However, when it is subjected to long-term aging at 800°C, a large number of rod-like Laves phases precipitate at grain boundaries and within the grain, leading to a significant reduction in its strength and toughness. Therefore, in the use of GH2696 alloy need to pay special attention to the impact of its aging treatment.
