The MMC of 6061 + 4%B4C and 1545 K + 4%B4C were successfully produced by stir casting techniques.
- class="label">•
Novel stir casting technique was used - the particles incorporated to the melt by powder master alloy.
- class="label">•
Good interface reaction between the matrix and the B4C reinforcements was observed.
