Synthesis of Ti3SiC2 by Pressureless Sintering of Compacted Powder Blends of Ti, SiC, C and TiC

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...

Synthesis of Ti3SiC2 through Pulse Discharge Sintering Powder Mixture Containing Coarse Ti

Ternary compound Ti3SiC2 was successfully synthesized by pulse discharge sintering (PDS) for Ti/Si/TiC powder mixtures with different molar ratios, where coarse Ti powder ( 0:15mm) was used. When the molar ratio of Ti:Si:TiC was selected to be 2:2:3, the content of Ti3SiC2 reached 97.8% and density reached 99.0% after sintering at 1450 C for 20min under 50MPa load. The Ti-Si liquid reaction occ...

Fabrication and inspection of C/Cf-ZrB2-ZrC-SiC and C/Cf-ZrB2-SiC composite parts resistant to ablation by pressureless sintering method

In this research, the aim is to achieve strong and ablation-resistant composite parts C / Cf-ZrB2-ZrC-SiC and C / Cf-ZrB2-SiC by non-pressure sintering method. C / Cf-ZrB2-SiC samples were prepared using synthesized ZrB2 and SiC powders between layers of resin-impregnated carbon fabric. After pressing with pressure 5 times at 1600 وC and heat treatment for 2 hours in a controlled atmosphere fur...
