Preparation of mullite whiskers reinforced SiC/Al2O3 composites by microwave sintering

However, at a mold extraction rate of 80 µm/s, the grain structure consisted of columnar grains aligned in the radial direction and SiC particles were observed throughout the

Figure 4 shows the effect of SiC content and its particles size on yielding point (YP), ultimate tensile strength (UTS) and elongation of Al-SiC composite that produced with

ZrC-SiC nanopowders were prepared by carbothermal reduction of ZrO 2 and SiO 2 with carbon black in argon gas atmosphere, using microwave energy as an alternative heating

C composites obtained higher bending strength values (Figure 5) than all other specimens because of higher density and excellent bonding of Al and ZrB 2 reinforcement particles

that radiation-indued interfae trap generation at the n-6H-SiC/SiO2 interfae is muh lower than.. at

small enough that, at the onditions of SiC growth, it failitates the SiC polytype formation..

The hydrothermal method combined with microwave heating allowed to obtain sheet-like (BiO) 2 CO 3 particles at shorter reaction times when compared to the conventional

The topographic analyses of the treated ceramic surfaces suggest that the airborne abrasion with SiO x particles (Figures 5B and 5D) promoted silica coating on the surface,
