The dual-phase AlCoCrFeNi2.1 eutectic high-entropy alloy (EHEA) presents a promising solution to the strength-ductility trade-off dilemma, making it highly desirable option for structural materials with vast potential applications. However, relationship between mechanical properties and unique as-cast heterostructures needs be further revealed. Here, we conducted in-situ tensile experiments of EHEA unveil mesoscopic/microscopic microstructural mechanisms synergy via investigating dynamic...
Fe-TiB2 composite shows great potential in lightweight materials for automotive parts due to its lightweight, high strength and specific modulus etc. However, challenges remain with regard establishing a fine hot working process of composites. Here, series isothermal compression tests was conducted systematically investigate the microstructure evolution dynamic recrystallization (DRX) mechanisms as-cast composites at different sets deformation parameters. The results indicate true stress...
TiN0.3/onion-like carbon (OLC) composites under high pressures and temperatures (HTHP) of 5.0 GPa 1100-1400 °C for 10 min. The microstructure mechanical properties TiN0.3 with different OLC contents were studied systematically. Experimental results showed that dual effect a concentration N vacancies temperature, the C atoms in diffuse into forming TiC0.3N0.7. hardness decreased increase onion-like content. When volume fraction was reduced to 5%, graphite lubricant phase still produced...
Research on how to obtain Si3N4 composites with high hardness and toughness at lower temperatures is important. onion-like carbon (OLC)-TiN0.3 were prepared using pressure temperature techniques. The effects of TiN0.3 OLC additives the mechanical properties microstructure silicon nitride ceramics analyzed. During sintering process, vacancies in promoted formation TiC0.3N0.7 interface between three compositions, whose particles homogeneously dispersed matrix strong bonding substrate....
In this study, short carbon fiber (SCF) and vapor-grown nanofiber (VGCNF) reinforced aluminum (Al) matrix composites were prepared by spark plasma sintering (SPS). The effects of different reinforcement on the microstructure evolution properties hot-rolled investigated. results demonstrate that SCF is more homogeneously distributed in Al matrix, VGCNF agglomerated because its smaller size. low interfacial strength between clusters a poor enhancement. generation products leads to high matrix....
With important research significance how to obtain Si3N4 composites with both high hardness and toughness at lower temperatures. Around this key issue, materials fixed amounts of onion-like carbon (OLC) TiN0.3 adjusted in the range 0-10vol% were prepared by spark plasma sintering. The effects OLC additives on mechanical properties microstructure silicon nitride ceramics comprehensively analyzed. significantly promoted phase transformation composites, 1500°C, completely transformed. presence...
