Abstract
Crystallization behavior of melt aluminum on the surfaces of SiC whisker (SiCw) was analyzed based on the consideration to obtain the SiC-Al interfaces with the lowest energy in SiCw/Al composite. The interfacial structure was investigated to determine whether a specific orientation relationship exists between SiC and Al. Analysis results indicate that four kinds of orientation relationships possibly exist between SiC and Al when only the <110> crystal direction of the aluminum is considered as the firstly formed crystal direction along the concave joint line of <110> of the SiC whisker. Interfacial atom match bonding models were set up in theory and one kind of crystal orientation relationship has been proved by our previous experimental result.
