<jats:p>New composite metal foams are processed using powder metallurgy (PM) and gravity
casting techniques. The foam is comprised of steel hollow spheres, with the interstitial spaces
occupied by a solid metal matrix (Al or steel alloys). The cyclic compression loading of the
products of both techniques has shown that the composite metal foams have high cyclic stability
at very high maximum stress levels up to 68 MPa. Under cyclic loading, unlike other metal
foams, the composite metal foams do not experience rapid strain accumulation within collapse
bands and instead, a uniform distribution of deformation happen through the entire sample until
the densification strain is reached. This is a result of more uniform cell structure in composite
metal foams compared to other metal foams. As a result, the features controlling the fatigue life
of the composite metal foams have been considered as sphere wall thickness and diameter,
sphere and matrix materials, and processing techniques as well as bonding strength between the
spheres and matrix.</jats:p> |
