Some structures or components of coastal buildings are often in an unsaturated state between drying and wetting conditions, and their performance deterioration is extremely serious. This paper mainly studied Cl diffusion of coral aggregate concrete under the coupled erosion of drying-wetting cycles, sulfate and chloride salts. Based on the microscopic morphology of corroded concrete, the erosion mechanism

Design and properties of self-healing superhydrophobic CNT@SiO2 coating for anti-icing application J. Mater. Res. Technol. (IF 6.4) Pub Date : 2024-04-04 Zongjing He, Huining Xu, Yu Zhou, Yiqiu Tan
Superhydrophobic coatings have aroused great research interest due to their potential applications in aviation, energy, etc. However, the coatings are inclined to lose hydrophobicity when exposed to chemical corrosion, which makes them difficult to play a crucial role in some demanding areas such as road engineering. Self-healing of coatings without external stimulations is challenging but essential

Molten salt corrosion behavior of laser remelted PS-PVD YSZ thermal barrier coatings J. Mater. Res. Technol. (IF 6.4) Pub Date : 2024-04-04 Qijie Zhou, Jiao Wen, Yuqi Li, Jianmin Han, Bangyang Zhou, Hongbo Guo, Jiebo Li, Jian He
Molten salt from the service environment leaches YO from yttria-stabilized zirconia (YSZ), threatening the security of thermal barrier coatings (TBCs). In this study, we compared the molten salt corrosion resistances of YSZ coatings prepared plasma-spraying physical vapor deposition (PS-PVD) before and after laser remelting. At 1000 °C, the molten salt reacted with YSZ particulates in the PS-PVD YSZ

Rapid heat treatment yields excellent strength and ductility balance in a wear-resistant steel J. Mater. Res. Technol. (IF 6.4) Pub Date : 2024-04-04 En Tang, Qing Yuan, Rui Zhang, Jie Ren, Zhongbo Li, Guang Xu
The rapid heating treatment with different tempering temperatures of 160, 200 and 320 °C was innovatively applied in one developed martensitic wear-resistant steel. The elaborate characterization on the evolution of microstructure-mechanical properties including the wear performance in different tempering temperatures were compared. Results manifested that the rapid heating treatment yielded a peak

Predicting the strain hardening behavior and constructing processing maps of a lightweight Fe–Mn–Al–C steel through phenomenological modelling J. Mater. Res. Technol. (IF 6.4) Pub Date : 2024-04-04 Iman Rahimi, Hamid Reza Abedi
This research deals with predicting the strain hardening behavior and constructing the processing maps of a lightweight steel over a wide range of temperature. To achieve this, the tensile tests were conducted at temperatures of 100 °C–1100 °C under strain rates of 0.001, 0.01, and 0.1s up to fracture. In order to predict the deformation behavior of the lightweight steel, strain compensated Arrhenius-type

Pre-hydrogenation metallurgy for Ti-3Al-5Mo-4.5V alloy with high density and mechanical properties J. Mater. Res. Technol. (IF 6.4) Pub Date : 2024-04-04 Guangyu Ma, Yuchao Song, Tuo Cheng, Long Yuan, Hailong Jia, M. Ivasishin Orest, G. Savvakin Dmytro
The present work proposes a novel master-alloy pre-hydrogenation powder metallurgy (MAPH) method to fabricate the TC16 (Ti-3Al-5Mo-4.5V) alloy, which overcomes the challenge of low sintering density due to the high percentage of alloying powders (APs) and the presence of Mo element. The relative density of sintered TC16 alloys increases with the Ti-addition in APs, i.e., ∼99.2% and ∼99.4% for sintered
