Tribology of Coated 316L SS by Various Nanoparticles by Dhiaa J. Aldabagh, Thair L. Alzubadi, Akram F. Alhuwaizi

“…The objective of the current research was to explore the tribological behavior, namely, friction of nanocoated thin layer by tantalum (Ta), niobium (Nb), and vanadium (V) manufactured using plasma sputtering at 1, 2, and 3 hours on substrates made of 316L stainless steel (SS), which is thought to be one of the most popular alloys for stainless steel orthodontic archwires. …”

Dramatic improvement in strength–ductility balance of dual-phase steels by optimizing features of ferrite phase by Kohei Ogatsu, Toshio Ogawa, Ta-Te Chen, Fei Sun, Yoshitaka Adachi

“…By controlling the annealing process, the hardening of the recrystallized ferrite grains due to niobium carbide precipitation was also observed. These results indicate that fine, equiaxed, and hardened recrystallized ferrite grains can be formed by adding Nb, selecting martensite as the initial microstructure, and performing controlled annealing. …”

High‐performance visible and near‐infrared dual‐band photodetector based on anisotropic 2D NbS3 with perpendicularly reversed polarization behaviors by Jidong Liu, Haibo Gan, Qiaoyan Hao, Yonghong Zeng, Youning Gong, Jiaqi Zhu, Jiarui Huang, Fei Liu, Wenjing Zhang

“…In this study, a visible and near‐infrared (NIR) dual‐band polarimetric photodetector with a single light‐absorbing layer is constructed by utilizing the distinctive conversion of linear dichroism (LD) polarity in two‐dimensional niobium trisulfide (NbS3). The NbS3 photodetector exhibits selective detection behaviors in the visible and NIR bands, in which by switching the polarization angle of the incident light from 0° to 90°, photocurrent decreases in the visible region, and increases in the NIR region. …”

Critical raw material-free multi-principal alloy design for a net-zero future by Swati Singh, Mingwen Bai, Allan Matthews, Saurav Goel, Shrikrishna N. Joshi

“…To assess the efficacy of these reduced-CRM MPEAs, we compared the hardness of newly synthesized MPEA with CRM-containing counterparts reported in the literature, particularly those with high-risk critical raw materials like Niobium (Nb) and Tantalum (Ta). For example, the CoCrFeNb0.309Ni alloy, which includes CRMs Nb and Co exhibits a Vickers hardness of 480 HV. …”
