We study the elastic moduli and structure of boron car-
bide/aluminum (B4C/Al) multiphase composites using rig-
orous bounding and experimental characterization tech-
niques. We demonstrate that rigorous bounds on the
effective moduli are useful in that they can accurately pre-
dict (i) the effective elastic moduli, given the phase moduli
and volume fractions, or (ii) the phase moduli (volume frac-
tions), given the effective moduli and phase volume frac-
tions (moduli). Using the best available rigorous bounds on
the effective elastic moduli of multiphase composites involv-
