摘要:
Two types of Al matrix composites (AMCs) containing micro-sized B4C particles (m-B4C/Al) and nano-sized particles (n-B4C/Al) were prepared by hybrid accumulative roll-bonding. The influences of m-B4C and n-B4C particles on the microstructure and mechanical properties of the AMCs were investigated systematically. Microstructure observations showed that B4C particles were uniformly distributed in the matrix with well-bonded interfaces in both the two types of composites. The n-B4C/Al composites presented finer grain size compared to the m-B4C/Al, indicating that n-B4C particles are more effectiv...
