it may be because of the lack of bonding between fillers and matrix, which process of fabrication you have used. Take a microstructure of the sample and you will get the reason i hope

Erik Carton

During the high temperature (sintering or liquid metal infiltration) the AA has reacted with the B4C to form various AlxByCz components. therefore there is hardly metallic AA left in the material....

Upon EDM you will not see much AA, let alone a high MRR.

Vikas Shrivastava

If the interfacial bonding is not good, MRR will be more in the case of composite. Secondly, if you are using powder metallurgy route, MRR will be more as compared to casting, if optimization of parameters is not done properly.
