The results show that with the increase of ball milling times, the yield of sBN is %, %, % and %, respectively. It can be seen that the yield of sBN is on the rise with the increasing milling times. This indicates that as the ball milling time increases, the exfoliation efficiency BN is gradually higher.

Reinforcement types have an important role in ballmilling behavior of the composite powders. The morphology of the three composites powders (Fig. 3) shows that the NCHEA particles are almost fully wrapped in the Al matrix after ball milling, which contributes to a uniform distribution of the NCHEA p in the composite powders. SiC particles ...
