321 phases are an atypical series of MAX phases, in which A = As/P, with superior elastic properties, featuring in the MA-triangular-prism bilayers in the crystal structure. Until now, besides Nb3As2C, the pure phases of the other 321 compounds have not been realized, hampering the study of their intrinsic properties. Here, molten-salt sintering (MSS) and solid-state synthesis (SSS) were applied to

Serrated flow accompanied with dynamic type transition of the Portevin–Le Chatelier effect in austenitic stainless steel J. Mater. Sci. Technol. (IF 10.319) Pub Date : 2022-07-12 Seung-Yong Lee, Sita Chettri, Ritupan Sarmah, Chikako Takushima, Jun-ichi Hamada, Nobuo Nakada
In order to further understand high-temperature deformation behavior and its-related mechanical properties, the Portevin–Le Chatelier (PLC) effect in an Fe–19Cr–13Ni–0.2C austenitic stainless steel was investigated using high-temperature digital image correlation (DIC) analysis. Under the tensile testing at temperatures from 473 to 623 K, different types of serrated flow appeared even at a constant

Construction of three-dimensional hierarchical porous nitrogen-doped reduced graphene oxide/hollow cobalt ferrite composite aerogels toward highly efficient electromagnetic wave absorption J. Mater. Sci. Technol. (IF 10.319) Pub Date : 2022-07-06 Jing Xu, Ruiwen Shu, Zongli Wan, Jianjun Shi
The development of graphene-based composites with low density, robust absorption, wide bandwidth and thin thickness remained a great challenge in the field of electromagnetic (EM) absorption. In this work, nitrogen-doped reduced graphene oxide/hollow cobalt ferrite (NRGO/hollow CoFe2O4) composite aerogels were constructed by a solvothermal and hydrothermal two-step route. Results demonstrated that

Magnetic-conductive bi-gradient structure design of CP/PGFF/Fe3O4 composites for highly absorbed EMI shielding and balanced mechanical strength J. Mater. Sci. Technol. (IF 10.319) Pub Date : 2022-07-10 Qiang Peng, Meng Ma, Si Chen, Yanqin Shi, Huiwen He, Xu Wang
Developing excellent absorption-dominant electromagnetic interference (EMI) shielding composites is an urgent demand for the rapid development of 5 G technology and electronic equipment. Herein, a simple strategy is employed to fabricate carbon nanotubes-polypropylene fibers (CP) /polypropylene-glass fibers felt (PGFF)/Fe3O4 composites with superior EMI shielding effectiveness and low reflection due
