“…MA6000 alloy is an austenitic Ni-based superalloy, reinforced by oxide dispersion strengthening (ODS) and γ’-phase precipitation hardening via mechanical alloying [1–3]. The addition of refractory elements, such as Cr, W, and Ta, to the Ni matrix, imparts remarkable features to the MA6000 alloy, including high creep and rupture resistance and excellent sulfidation and corrosion resistance, particularly when operating in high-temperature and ambient environments [2,4,5]. The exceptional attributes of the MA6000 alloy indicate it as a strong candidate for use in high-temperature industrial processes, especially as an uncooled turbine blade material [6,7].…”

The present study investigates the properties and microstructure evolution of MA 6000, a nickel-based alloy produced by mechanical alloying and spark plasma sintering (SPS), a powder processing technique in metallurgy. This study aims to explore the potential of MA 6000 as a high-temperature material for industrial applications. Modified MA 6000 samples of different powder sizes were sintered in a high-vacuum environment at temperatures ranging from 800 to 1100°C. At 800°C, the cohesion between powder particles was not significant, resulting in low-density samples. However, at 1000°C, the samples consisted of many fully sintered regions related to finer powder particles, while no specific morphology was observed at 1050°C. The image quality and inverse pole figure (IQ-IPF) map indicated that the grains were distributed randomly in all sintered samples, and the average distribution of grain size of samples sintered at 1050°C was larger than that of those sintered at 1000°C.
