Synthesis and Sintering of Ti3SiC2–SiC Composites through Reactive Hot-Pressing of TiC and Si Precursors

MAX phases are an attractive class of layered solids that have recently attracted a great deal of attention due to their unusual and unique composition. The ternary compound Ti3SiC2 is an example of a material that combines the properties of ceramics and metals. As a ceramic, they are high stiff. Some of them are resistant to oxidation, creep, fatigue, corrosion. They are extremely refractory a...

Reactive Sintering of TiAl - Ti 5 Si 3 Lnsitu Composites

TiAl with between 0 and 20 volume percent (v%)Ti5Si3 was produced by reactive sintering of cofd pressed compacts of elemental Ti, Al and Si powder mixtures at 7OO0C for 15 minutes in vacuum. The results show that adding Si to Ti and A1 reduces the swelling associated with reactive sintering of TiAI, as composites containing more than 5 vYoTigSi3 densified during reactive sintering. However, com...

Pore Formation Process of Porous Ti3SiC2 Fabricated by Reactive Sintering

Porous Ti3SiC2 was fabricated with high purity, 99.4 vol %, through reactive sintering of titanium hydride (TiH2), silicon (Si) and graphite (C) elemental powders. The reaction procedures and the pore structure evolution during the sintering process were systematically studied by X-ray diffraction (XRD) and scanning electron microscope (SEM). Our results show that the formation of Ti3SiC2 from ...

AN INVESTIGATION ON REACTIVE SINTERING OF NANO-CRYSTALLINE TiO2 -Al POWDER PREPARED BY MECHANICAL ALLOYING

In this research an ultra-fine grained composite structure consisting of an intermetallic matrix together with dispersed nano-sized Al2O3 obtained via mechanical activation of TiO2 and Al in a high energy ball mill and sintering of consolidated samples. Phase composition and morphology of the milled and sintered samples were evaluated by XRD and SEM techniques Thermal behavior of the powder sa...
