Processing of A1-Li alloy composite with submicron SiC particle reinforcement by mechanical alloying

The present study was undertaken with the primary objective of solving the agglomeration problem of submicron SiCp(0.8 urn) in the Al-Li alloy(8090) composite. Several mixing methods, particularly mechanical alloying (MA), were employed to mix sub-micron SiCp with Al-Li alloy powders. Results showed...

Description
Summary:The present study was undertaken with the primary objective of solving the agglomeration problem of submicron SiCp(0.8 urn) in the Al-Li alloy(8090) composite. Several mixing methods, particularly mechanical alloying (MA), were employed to mix sub-micron SiCp with Al-Li alloy powders. Results showed that the uniform dispersion of SiCp among the matrix powders was achieved by mechanical alloying with the appropriate parameters, namely 200 rpm for 8 hours.
