Mechanical Properties of SiC Short-Fibre-Reinforced SiC Composites Fabricated by Tape Casting and Hot-Pressing

Casting of SiC Reinforced Metal Matrix Composites

Composites based on two aluminium alloys (A536 and 6061) reinforced with 10% or 20% volume fraction of SiC particles were produced by gravity casting and a novel two-step mixing method was applied successfully to improve the wettability and distribution of the particles. The SiC particles were observed to be located predominantly in the interdendrit ic regions, and a thermal lag model is propos...

Mechanical Properties of SiC Fiber- Reinforced Reaction-Bonded Si3N4 Composites

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...

Effect of Pre-Oxidation Treatment of Nano-SiC Particulates on Microstructure and Mechanical Properties of SiC/Mg-8Al-1Sn Composites Fabricated by Powder Metallurgy Combined with Hot Extrusion

Nano-SiC particulates (n-SiCp) reinforced Mg-8Al-1Sn (AT81) composites with different pre-oxidation parameters were fabricated by powder metallurgy (P/M) process combined with hot extrusion. The effects of pre-oxidization treatment of n-SiCp on the microstructure and tensile properties of 0.5 vol % n-SiCp/AT81 composites were investigated accordingly. The distribution of n-SiCp with different p...
