Functionally Graded Materials (FGMs) offer discrete or continuously changing properties/
compositions over the volume of the parts. The widespread application of FGMs was not …

The current review uses the material requirements of a new space propulsion device, the
Variable Specific Impulse Magnetoplasma Rocket (VASIMR®) as a basis for presenting the …

Abstract Functionally Graded Materials (FGM s) represent a novel approach for the
realization of innovative properties and/or functions that conventional homogeneous …

Si 3 N 4 ceramics were sintered at 1900° C under a nitrogen pressure of 1 MPa using Y 2 O
3-MgO additives. The effects of Y 2 O 3 content (0.5-4 mol%) on microstructure and thermal …

Sialons are the spotlight of current investigation as low-cost and outstanding alternatives to
the currently used metal alloys in various applications. The excellent high-temperature …

In multilayered structures, sharp interface is formed between the layers of dissimilar
materials. At this interface, the large difference in thermal expansion coefficients of the two …

Functionally graded SiAlON ceramics (FG‐SiAlONs) were successfully prepared by the tape
casting and lamination approach. Non‐aqueous SiAlON slurries with five different α to β …

Functionally graded materials (FGMs) have attracted more and more attention due to their
graded changes on composition or microstructure to satisfy some conflicting properties in …

Fine β‐sialon (Si6− zAlzOzN8− z, 1< z< 4) was prepared by mechanical‐activated
combustion synthesis (CS) using raw materials such as Si, Al, and SiO2 in a nitriding …

Single phase α-, β-and two phases α/β-sialon composites were sintered with both Nd2O3
and Yb2O3 by hot isostatic pressing (HIP). The mechanical and tribological properties of …
