Inconel MA754

INCONEL alloy MA754 (UNS N07754) is an oxide dispersion strengthened, nickel-chromium superalloy, produced by mechanical alloying. Its yttrium oxide dispersoid imparts exceptional high-temperature strength and creep resistance to the highly corrosionresistant nickel-chromium matrix.

The alloy's strength, in conjunction with its high melting point and microstructural stability, makes it an attractive material for gas turbine engine components, furnace fixtures and skid rails, fasteners and other applications where high temperature creep and corrosion resistance are required.

Mechanical Properties

INCONEL alloy MA754 develops optimum high-temperature strength through controlled thermo-mechanical processing designed to create a stable, recrystallized, coarse grain structure. Plate products are processed to achieve isotropic properties.

INCONEL alloy MA754 can be processed to have a highly textured crystallographic structure, producing excellent resistance to thermal fatigue. In such a condition, the properties are anisotropic. Elastic properties are also affected by the crystallographic texture. In this condition, the ODS mechanism is augmented, for superior mechanical properties in the longitudinal direction, by the high aspect ratio grain structure. The highly directional structure is responsible for anisotropic mechanical properties. For applications that require exceptional resistance to thermal fatigue, like gas turbine vanes, INCONEL alloy MA754 is given a strong texture with a <100> crystallographic direction parallel to the working direction. Such texture results in a low modulus of elasticity in the longitudinal direction, improving resistance to thermal fatigue by lowering stresses for given thermal strains.

Corrosion Resistance

INCONEL alloy MA754 has excellent oxidation resistance. It may be used in high-temperature oxidizing environments without the need for expensive special coatings usually required for conventional high-temperature alloys.

The nature of the alloy's protective scale, and its high nickel content, provide excellent resistance to nitridation.
