Combined role of SiC particles and SiC whiskers on the characteristics of spark plasma sintered ZrB2 ceramics
TL;DR: In this article, the effects of silicon carbide (SiC) as the most important reinforcement phase on the densification percentage and mechanical characteristics of zirconium diboride (ZrB2)-matrix composites were studied.
Journal ArticleDOI
Influence of TiB2 content on the properties of TiC–SiCw composites
Mehdi Fattahi,Yaghoub Pazhouhanfar,Seyed Ali Delbari,Shahrzad Shaddel,Abbas Sabahi Namini,Mehdi Shahedi Asl +5 more
TL;DR: The impact of various volume percentages of TiB2 additive (0, 10, 20, and 30) on the microstructure, relative density (RD), Vickers hardness, flexural strength, and thermal conductivity of as-sintered TiC-10-vol% SiCw-based composite samples were scrutinized as mentioned in this paper.
Journal ArticleDOI
Influence of SPS temperature on the properties of TiC–SiCw composites
Mehdi Fattahi,Ahad Mohammadzadeh,Yaghoub Pazhouhanfar,Shahrzad Shaddel,Mehdi Shahedi Asl,Abbas Sabahi Namini +5 more
TL;DR: In this article, the microstructural characteristics of the sintered samples were assessed by optical and field emission scanning electron microscopy (FESEM) and XRD, and the results revealed that at 1900°C, the dispersion of SiCw in the TiC matrix was homogenous, no chemical reaction took place between the reinforcement and the matrix, and produced a fine-grained microstructure.
Journal ArticleDOI
Role of graphite nano-flakes on the characteristics of ZrB2-based composites reinforced with SiC whiskers
Mehdi Shahedi Asl,Yaghoub Pazhouhanfar,Abbas Sabahi Namini,Shahrzad Shaddel,Mehdi Fattahi,Mohsen Mohammadi +5 more
TL;DR: In this paper, the role of nano-graphite on the structure, hardness, densification, and toughness characteristics of ZrB2-SiCwgraphite nanocomposites were inspected.
Journal ArticleDOI
Strengthening of novel TiC–AlN ceramic with in-situ synthesized Ti3Al intermetallic compound
Mehdi Fattahi,Yaghoub Pazhouhanfar,Seyed Ali Delbari,Shahrzad Shaddel,Abbas Sabahi Namini,Mehdi Shahedi Asl +5 more
TL;DR: In this paper, the impact of AlN addition and Ti3Al in-situ formation on the properties of SPSed ceramics was investigated, showing that AlN had a significant influence on the relative density of TiC due to the formation of molten Al and Ti 3Al intermetallic phase, yielding a fully dense material.
