Microstructures and Damping Properties in Ni-Al-Based Alloys


Article Preview

The binary Ni-rich Ni64Al36 (nominal compositions, all compositions are in atomic percent unless otherwise stated,) alloy and ternary Ni-21.2 Al-20 Fe alloy ingot were prepared by melting commercial pure Ni and pure Al in a vacuum arc furnace under an argon atmosphere. The ingots were then hot rolled into a rectangle with the length of 55 mm. The microstructures of Ni-Al-based alloys were investigated using optical microscope and X-ray diffraction. The damping capacity of oil-quenched ternary Ni-21.2 Al-20 Fe alloy from different temperature is investigated using a multifunctional internal friction apparatus.
