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

Effect of Repeated Thermal Shock on Mechanical Properties of ZrB2-SiC-BN Ceramic Composites

ZrB2-20 vol.% SiC-10 vol.% h-BN (particles) ceramic composites (ZSB) were fabricated by hot pressing under inert gas protected. ZSB samples with mean size 75 × 55 × 40 mm(3) were heated using current heating method and then cooled down to low temperature by circulating water. ZSB samples repeatedly went through thermal shock with 10-50 times under various conditions, respectively. Diverse effec...

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...

EFFECT OF FIBER ARCHITECTURE ON MECHANICAL BEHAVIOR OF SiC(f)/SiC COMPOSITES

We evaluated mechanical properties (first matrix cracking stress, strength, and work-of-fracture) of Nicalon-fiber-reinforced silicon carbide matrix composites with three different fiber lay-up sequences (0"/20"/60", O0/4Oo/6O0, and 0"/45") at various temperatures from room to 1300°C. Up to 1200"C, ultimate strength and work-of-fracture for the 0"/40"/60" and 0"/45" composites increased, but th...

Physio-mechanical Properties of Aluminium Metal Matrix Composites Reinforced with Al2O3 and SiC

Particulate reinforced metal matrix composites (MMCs) are potential materials for various applications due to their advantageous of physical and mechanical properties. This paper presents a study on the performance of stir cast Al2O3 SiC reinforced metal matrix composite materials. The results indicate that the composite materials exhibit improved physical and mechanical properties, such as, lo...
