Ceramic transactions functionally gradient materials.

It can be formed by varying chemical composition microstructure or design attributes. The optimum material gradient of a rectangular plate made of functionally graded material fgm is determined in this study. Elastic modulus of functionally graded fg rectangular plate is assumed to vary continuously throughout the height of the plate according to the volume fraction of the constituent materials based on the power law exponential model i exponential model i x41f i. Functionally gradient materials fgm are innovative materials in which final properties varies gradually with dimensions.

A tape casting process was used to prepare various al 2 o 3 tic green tapes from which laminated and functionally gradient al 2 o 3 tic materials fgm al 2 o 3 tic were produced by cutting stacking and laminating the material removing the binder and hot pressing the green bodies. Components of various ceramic materials with predetermined material gradients have been reported in recent studies 16 17. 1996 eisevier science limited and techna s r l. A green part with graded composition of alumina al 2 o 3 and zirconia zro 2 was also fabricated.

Functionally graded material fgm is a material with engineered gradients of composition structure and or specific properties aiming to become superior over homogeneous material composed of same. In materials science functionally graded materials fgms may be characterized by the variation in composition and structure gradually over volume resulting in corresponding changes in the properties of the material the materials can be designed for specific function and applications. It is the recent development in traditional composite materials which retains their strengths and eliminates their weaknesses. The bending strength of the fgm al 2 o 3 tic composites was not much less than that of the.

Developed an extrusion method to control the fabricate caco 3 composite with a graded color. Enables obtaining materials with composition and structure gradients having unprecedented properties.
