    Effects of GTAW process and post-welding heat treatment on the microstructure evolution, cracking behavior and hardness of Inconel 939 superalloy using Inconel 617 filler metal by Amir Hossein Jafarzadeh, Mohammad Saeed Shahriari, Rouholah Ashiri

    Published 2025-09-01
    “…The research focuses on three key challenges: (1) irregularities in pre-existing MC carbides, (2) heat-affected zone (HAZ) liquation cracking, and (3) post-weld heat treatment (PWHT) effects on microstructure evolution and hardness distribution. Initial welding revealed a 91 μm HAZ crack, identified as liquation cracking caused by localized melting of service-induced lamellar carbides along grain boundaries. …”

    The Microstructural Evolution and Mechanical Properties of Boron-Doped Ti<sub>35</sub>Zr<sub>30</sub>V<sub>10</sub>Nb<sub>25</sub> Refractory High-Entropy Alloy by Xinggang Wang, Meng Sun, Jiaxin Liu, Xueqing Liu, Weibin Jiang, Xianping Wang, Qianfeng Fang

    Published 2024-11-01
    “…In this work, boron-doped Ti<sub>35</sub>Zr<sub>30</sub>V<sub>10</sub>Nb<sub>25</sub> (Ti35-xB) refractory HEAs were designed to elucidate their microstructural evolution and mechanical properties. Unlike oxygen and nitrogen, trace amounts of boron addition result in the formation of borides, and boron exhibits a strong repulsion towards Zr, leading to Zr-depleted borides. …”
