20%
SiC Addition to Aluminum
The aluminum with
20% SiC addition exceeds the minimum requirements for modulus and strength, compared to
the unreinforced C 355-T6.
The fluidity of the
aluminum with 20% SiC addition meets the minimum fluidity requirements at the 775C pouring
temperature.
The specific modulus (modulus
divided by the density) for the 20% SiC addition has the highest value
(143.1 x 10^6 in) compared to values for baseline C355 and the 10% SiC-aluminum
alloy.
