In-situ planting nano-particles as ultra-fine networks into the TMCs powder and constructing the interfacial/intragranular hierarchical microstructure have emerged as a promising strategy to overcome the strength-ductility trade-off. In the present work, we precisely controlled the distribution of the network nano-particles by adjusting the sintering temperatures and successfully transformed the ultrafine network into the interfacial/intragranular structure. The well-designed (TiB + La<sub>2</sub>O<sub>3</sub>)/IMI834 TMCs demonstrated exceptional mechanical properties, achieving a tensile strength of 1158 MPa while maintaining an elongation exceeding 8.6 %F PUB:(DE-HGF)16 %9 Journal Article %R 10.1016/j.compositesb.2025.112737 %U https://bib-pubdb1.desy.de/record/636255
