Phenolic resin is an important binder for refractory ceramics. Herein, aluminum and organic rectorite were employed to improve the antioxidant activity of phenolic resin. X-ray diffraction revealed that the silicate layers of phenolic resin exfoliated rectorite were uniformly dispersed in the modified phenolic resin (MPF) matrix. Moreover, TEM revealed that the peeled silicate nanoparticles from rectorite were well distributed without clustering. The structure of the MPF resin was also analyzed by infrared spectroscopy and nuclear magnetic resonance. The results showed that the strength of the ether bridge of MPF resin with aluminum and rectorite considerably decreased than that of pure phenolic resin. The MPF resin was anhydrous and had Al O bonds to link the benzene rings. Pyrolytic carbon experiments revealed that the decomposition temperature of the MPF resin was 759.2 C, which indicated that it had a better oxidation resistance and bonding strength than those of pure phenolic resin. The incorporation of aluminum and rectorite improved thermal performance of the phenolic resin, and enhanced mechanical performance of the MgO C refractory.

“…Refractory masonry with dry joints is extensively used for the linings of several high temperature components such as steel ladles, furnaces and rotary kilns due to their high thermal, mechanical and chemical stability, good thermo-mechanical and thermo-chemical properties [1][2][3][4][5]. When used in steel ladles, they are subjected to high thermal gradients, thermal shock, cyclic thermal heating and cooling, high thermo-mechanical stresses, slag attack, and harsh chemical environment [6][7][8][9][10][11]. Therefore, the lifespan of steel ladles internal linings is very short (several castings).…”

Refractory masonry with dry joints is widely used in the steel-making industry for the linings of several high-temperature components (> 1500°C) including steel ladles and furnaces. To properly optimize the design and performance of these linings, thorough numerical models that consider the presence of joints, joints closure and reopening and the nonlinear elastic-viscoplastic behaviour (creep and stress relaxation) of refractories at high temperature are required. The present study reports on the formulation, numerical implementation, and application of a homogenized multi-scale elastic-viscoplastic model

“…The fracture phenomena in polycrystalline metals have inspired renewed interest in the mechanism of cracking when solid metals are in contact with liquid metals. Especially, in some material-processing scenarios, such as joint processes [1][2][3][4], galvanizing [5][6][7], heat treatment [8], smelting and solidification [9][10][11], hot working [12], nuclear industrial [13], microelectronics, data storage technology [14], corrosion science [15][16][17] etc. The understanding of the fracture mechanism will provide useful insights into the strengthening mechanisms of materials with novel structures or new perspectives on designing materials.…”

Self-induced internal corrosion stress transgranular cracking is investigated theoretically and experimentally linking grain boundary wetting (GBW) and grain boundary diffusion (GBD) to improve the ability to reveal the micro mechanism of crack in compositional gradient-structural intermetallic materials. Theoretical analysis shows that the grain boundary wetting and diffusion induce the diffusion-coupled dynamic internal stresses, and their interaction leads to crack nucleation. The experimental results show a stress concentration zone have been established at the grain boundary interface where the cracks preferentially nucleate and then extend through the inside of the grain to both sides, forming a typical transgranular fracture.
