Strength of hot-pressed SiC from Al doped .ALPHA.-SiC powder.

Observation of glassy ferromagnetism in Al-doped 4H-SiC.

Glassy ferromagnetism is observed in diluted magnetic semiconductor Al-doped 4H-SiC. We propose a possible explanation for the origin of ferromagnetism order that is the coeffect of sp(2)/sp(3) configuration along with the structural defects. This result unambiguously demonstrates the existence of intrinsic ferromagnetism order in nonmagnetic sp systems.

Nonlinear Thermal Expansion Model for SiC/Al

The thermal expansion behaviour of silicon carbide (SCS-2) fibre reinforced 6061 aluminium matrix composite subjected to the influenced thermal mechanical cycling (TMC) process were investigated. The thermal stress has important effect on the longitudinal thermal expansion coefficient of the composites. The present paper used experimental data of the thermal expansion behaviour of a SiC/Al comp...

Synthesis and Compressive Properties of Al-A206/SiC and Mg-AZ91/SiC Syntactic Foams

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...

Getting sick from Sic

and colleagues have found that certain successful Streptococci actually avoid attachment to host cells. This contrasts with the modus operandi of most pathogenic bacteria. The M1 serotype of the highly heterogeneous Group A Streptococcus (GAS) pathogen is the most common GAS strain found in severe disease outbreaks. M1 GAS are unique in that they produce streptococcal inhibitor of complement (S...
