Hj. Feng et Jj. Moore, THE EFFECT OF PRESSURE ON THE COMBUSTION SYNTHESIS OF A FUNCTIONALLY-GRADED MATERIAL - TIB2-AL2O3-AL CERAMIC-METAL COMPOSITE SYSTEM, Journal of materials engineering and performance, 2(5), 1993, pp. 645-650
This article describes some recent research on the synthesis of functi
onally-graded materials (FGM) using combustion synthesis or self-propa
gating high-temperature synthesis (SHS). A model ceramic-metal SHS sys
tem was investigated based on the reaction system: 3TiO2 + 3B2O3 + (10
+ x)Al = 3TiB2 + 5Al2O3 + xAl in which x was varied between 0 and 17
to achieve the required composition and phase gradients in the FGM. Th
e effects of combustion mode, reactant stoichiometry (xAl), green dens
ity, and applied loads on the stability of the SHS reaction and densit
y of the FGM product are described.
