Pressureless Infiltration Processing of B₄C/Al Composite by Surface Modification

ABSTRACT

Al 6061 disk on the$B_4C$preform and heating at $1030{circ}C$/20 min under a flowing argon, but no infiltration took place for a bare $B_4C$ preform even at$1250{circ}C$/30 min. Analysis of XRD and SEM showed the $Al_3BC$phase besides$B_4C$and Al, but no trace of deteriorative$A1_4C_3$.ᐊ愀Ѐ㔸ㄻ؀偬慮瑳
