Pressureless melt infiltrated non-oxide ceramic-metal composites
Kalemtaş, Ayşe; Arslan, Gökhan; Kara, Ferhat (2009)In the present study highly dense (open porosity > 1 %), light-weight (d ? 2.85 g/cm3) and Al4C3-free non-oxide ceramic-metal composites were produced at comparatively low temperatures (? 1250°C) by pressurless melt ... -
Processing of in-situ SiC reinforced AlN based composites
Kalemtaş, Ayşe; Arslan, Gürsoy; Kaya, Pınar; Turan, Servet; Kara, Ferhat (Korean Assoc Crystal Growth, Inc, 2018)In this study, highly dense (>97%) in-situ SiC reinforced AlN based ceramic-metal composites were produced by pressureless reactive infiltration of 7075 aluminium alloys into porous alpha-Si3N4, alpha-Si3N4 + 4 wt. % carbon ... -
Processing of silicon carbide-boron carbide-aluminium composites
Arslan, Gürsoy; Kalemtaş, Ayşe (Elsevier Sci LTD, 2009)The aim of this work was to shed light on the wetting mechanism in the SiC-B(4)C-Al system and to explore processing routes that enable infiltration of Al alloys into these ceramic powder mixtures without the formation of ... -
Thermal properties of pressureless melt infiltrated AlN-Si-Al composites
Kalemtaş, Ayşe; TopAteş, Gülsüm; Bahadır, Özlem; Kaya Isci, Pınar; Mandal, Hasan (Elsevier Science BV, 2013)Thermal properties of AlN-Si-Al composites produced by pressureless melt infiltration of Al/Al alloys into porous alpha-Si3N4 preforms were investigated in a temperature range of 50-300 degrees C. SEM and TEM investigations ...
