The Effect Analysis of Environment on Microstructure，Fracture Model and Mechanical Properties of Continuous Silicon Carbide Fibers [PDF]
, 2005 耐高温、高性能连续SiC纤维在航空航天和先进武器装备中具有特殊重要地位。SiC纤维作为陶瓷基复合材料的增强相（即复合材料的骨架），要求在高温服役环境下具有优良的热物理化学与力学性能的稳定性，这些性能显然与纤维的组成和微结构有关。因此，研究高温和有氧气氛处理对纤维的力学性能与微结构的影响，对于认识SiC纤维在服役环境下的失效机理，正确评价纤维的高温环境性能，指导纤维组分与微结构设计具有重要指导作用。国外从上世纪90年代末已经开始在这方面进行了一些研究 ...

Nitrogen Anchoring Effect Triggering Improved Reversible Hydrogen Storage of Mg(BH4)2
Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT This research uncovered the influence of nitrogen‐doped MXene Ti3CN on the reversible hydrogen storage properties of Mg(BH4)2. The Mg(BH4)2‐20Ti3CN composite began releasing hydrogen at a temperature of 80°C. In addition, the composite discharged over 8.8 wt% hydrogen at a comparatively lower temperature of 270°C, whereas the pure Mg(BH4)2 ...
