Heating of sole urea in the same conditions is a well-known method to prepare C<sub>3</sub>N<sub>4</sub>. However, none of these phases is formed upon heating of a mixture of sulfur, HMA and urea, but the product has a complex high entropy Mo–C–N–O–S composition in which four light elements are randomly distributed around the Mo atoms. These solids remain amorphous and keep high surface area even at 550 °C, but disproportionate at 750 °C. The Mo–C–N–O–S solids prepared via this extremely simple one-pot synthesis route were studied by several techniques including X-ray absorption spectroscopy (XAS) and transmission electron microscopy (TEM). The materials are mesoporous and show promising HER activity in acidic conditions. Reaction mechanism leading to the mixed phase was studied by thermal analysis coupled with mass-spectrometry. XAS study demonstrated that Mo is surrounded by light atoms and has a small number of Mo neighbors. Remarkably, Mo species remain ultradispersed in the solids containing even 40 wt% of the metal.

The purpose of this research is to study the influence of annealing heat treatment on the anisotropy properties and its relationship with the formability behavior of three-layer brass (CuZn10)/steel (St14)/brass (CuZn10) composite sheet. The samples were fabricated using the cold roll bonding (CRB) process, annealed at different temperatures for two hours, and cooled in the furnace. The uniaxial tensile test was performed in different directions (0°, 45°, 90°), and the anisotropy value of the samples was obtained using the digital image correlation (DIC) method. The formability of the samples was determined experimentally through the forming limit diagram (FLD) by the Nakazima test. The results indicated that the value of normal anisotropy (r<sub>m</sub>) increases with the increase of annealing temperature. This trend for FLD<sub>0</sub> is similar to the anisotropy changes, which shows that increasing the annealing temperature improves the formability behavior of the three-layer composite. However, the changes in FLD<sub>0</sub> and <i>r</i><sub><i>m</i></sub> at different annealing temperatures are not the same, which can be attributed to the occurrence of recrystallization in steel and brass layers. For this purpose, the microstructure and grain size of the steel layer were examined by an optical microscope (OM).

Comparing with the oxygen crosslinking, thermal crosslinking can reduce the introduction of oxygen within fibers. In this study, a novel method for preparing the SiC fibers was proposed by combining dry spinning and thermal crosslinking. The spinning solution was prepared by blending a low-molecular-weight (~ 1000 Da) polycarbosilane (PCS) with polyisobutene (PIB) as spinning additive, acrylic acid (AA) as crosslinking agent, and 2,2'-Azobis (2,4-dimethyl) valeronitrile (ABVN) as initiator. The crosslinking mechanism, morphology, composition and microstructure, and mechanical properties of fibers were investigated. The results showed that the morphology of AA-containing PCS fibers was well preserved at 300 ℃ with a low heating rate (0.5 ℃/min), while PCS fibers without AA exhibited the melting or deformation. The crosslinking reaction between C = C groups in AA-containing PCS and Si–H bonds in PCS was triggered by ABVN. Furthermore, AA-containing PCS green fibers experienced pyrolysis at 1100 ℃ and then were annealed at 1500 ℃ (denoted as SiC-1500). SiC-1500 fibers, with an average diameter of 10.47 ± 0.50 μm and average tensile strength of 1.35 ± 0.65 GPa, have a smooth surface and relative dense structure. But SiC-1500 fibers were still an amorphous structure due to the suppression of graphite phase for the growth of β-SiC grains. This work not only breaks through the limitations that only uses high-molecular-weight PCS for dry spinning, but also successfully combines dry spinning and thermal crosslinking technology to obtain SiC fibers.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":645,"journal":{"name":"Journal of Materials Science","volume":"59 45","pages":"20929 - 20943"},"PeriodicalIF":3.5,"publicationDate":"2024-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142736831","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
