| Dispersion of Ceramic Powders Into Particulate Superplastic Al-Li Alloy. (1998) | |||||||||
Abstract | |||||||||
| A new method for dispersing homogeneously fine ceramic powders into a particulate alloy matrix has been developed; the Al-Li matrix alloy, with controlled crystal grain size and shape, shows superplastic behavior under certain conditions; the homogeneous dispersion of SiC in the matrix alloy was achieved by introducing the fine particles of filler along the grain boundaries within the alloy particles; this new compounding method yields a composite powder (i.e. each particle itself is a composite) rather than a mixture of different components. | |||||||||
