Symmetrical triangular waveforms and strain amplitudes ranging from ±0.4 to ±0.8% were used to study LCF behaviour at room temperature. The fatigue life of additive manufactured and solution-treated (AM-ST) samples was found to be improved, due to better carbide homogenisation and reduced defect volume compared to that of AM-AR IN625. Fatigue life was improved by 2000-3000 cycles after solution treatment. A continuous cyclic hardening was observed till peak stress level at all strain amplitudes. The number of cycles to failure was found to decrease with rise in strain amplitude. TEM micrographs revealed the solute-dislocation pinning interactions. SEM fractography revealed the striations in the slow crack propagation zone and dimples due to microvoid coalescence in the fast propagation zone.","PeriodicalId":344,"journal":{"name":"Journal of Alloys and Compounds","volume":"4 1","pages":""},"PeriodicalIF":6.2,"publicationDate":"2025-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143876351","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results showed that the MIL-53(Fe)/SnS₂-3% (3% is the mass ratio of SnS₂ to MIL-53(Fe)) displayed the highest activity reaching a RhB (10<!-- --> <!-- -->mg/L, 100<!-- --> <!-- -->mL) removal rate of 85.6% within 60<!-- --> <!-- -->min with catalyst and PMS dosage of 0.1 and 0.1<!-- --> <!-- -->g/L, respectively.

The enhanced performance of MIL-53(Fe)/SnS₂/PMS system can be attributed to the Z-scheme heterojunction formed between MIL-53(Fe) and SnS₂, which inhibits the recombination of photogenerated electron-hole pairs. The PMS activation mechanism by MIL-53(Fe)/SnS₂ was proposed based on the detailed catalyst characterization, degradation efficiency tests, electron paramagnetic resonance and radical quenching experiments. Furthermore, the MIL-53(Fe)/SnS₂ exhibited good stability and suitability for different environmental conditions.

The analysis by scanning-electron microscopy revealed that BiOCl photocatalysts made with urea and thiourea had irregular-like and rod-like shapes, respectively. The BiOCl photocatalyst synthesized with urea and thiourea degraded Methylene Blue (MB) by 90% and 100%, respectively, after 90&lt;!-- --&gt; &lt;!-- --&gt;min under UV-VIS light. Interestingly, BiOCl photocatalyst made with thiourea degraded completely MB after only 60&lt;!-- --&gt; &lt;!-- --&gt;min under solar light. Later, the BiOCl photocatalyst was supported on recycled rubber (taken from bicycle tires) and this rubber/BiOCl (R/BiOCl) composite produced 100% degradation for MB after 90&lt;!-- --&gt; &lt;!-- --&gt;min of photocatalytic reaction. BiOCl powder synthesized with thiourea also degraded totally Rhodamine B (RhB) dye (after 90&lt;!-- --&gt; &lt;!-- --&gt;min using UV-VIS light and after 10&lt;!-- --&gt; &lt;!-- --&gt;min using sunlight). The R/BiOCl composite degraded 100% of RhB after 120&lt;!-- --&gt; &lt;!-- --&gt;min. Thus, the R/BiOCl composite produced slower dye degradation, but it was easily removed (manually) from the clean water. BiOCl synthesized with thiourea produced the highest photocatalytic performance because: i) it had the highest absorbance in the UV-VIS range and ii) it had the highest content of defects, which promoted the photocatalytic activity. In fact, BiOCl made with thiourea induced the highest mineralization of carbon (86%) according to the TOC analysis. Additionally, the incorporation of Er and Yb ions into the BiOCl lattice facilitated the Up-conversion process under solar irradiation, enhancing the generation of electron-hole pairs, which in turn, incremented the photocatalytic degradation of MB and RhB dyes.
