    Effects of Heat Treatment on Microstructures and Corrosion Properties of Al<i><sub>x</sub></i>CrFeNi Medium-Entropy Alloy by Pushan Guo, Yuan Pang, Qingke Zhang, Lijing Yang, Zhenlun Song, Yi Zhang

    Published 2025-03-01
    “…This study designed Al<i><sub>x</sub></i>CrFeNi (<i>x</i> = 0.8, 1.0, 1.2) medium-entropy alloys featuring a BCC + B2 dual-phase structure to systematically investigate the effects of Al content variation and heat treatment on microstructure evolution and corrosion behavior. Microstructural characterization revealed that all investigated alloys maintained the BCC + B2 dual-phase labyrinth structure. …”

    Evolution of Precipitates and Microhardness of L-PBF Inconel 625 Through Relevant Thermal Treatment by Tahmina Keya, Ralf D. Fischer, Mohanish Andurkar, Scott M. Thompson, Valentina O’Donnell, John Gahl, Barton C. Prorok

    Published 2024-12-01
    “…The alloy is prone to precipitation under elevated temperatures, which makes designing suitable heat treatment to tailor the desired microstructure and mechanical properties critical. Traditional heat treatment for wrought IN625 cannot be applied to L-PBF IN625; therefore, it is vital to understand the evolution of precipitates on the way to complete recrystallization. …”
