Abstract
In this work, we report on the reaction of molten aluminum with Ti3SiC2 in the 800-1000 degreesC temperature range. The reaction kinetics are linear a nd follow the relation: K-0 (m s(-1)) = 7.16 exp - (207 kJ/RT). The reactio n layer consists of two interconnected or interpenetrating networks of TiC0 .67 and molten Al. The samples preserve their original shape and dimensions after the reaction. Some TiC particles, as well as TiAl3 platelets are som etimes observed in the Al bath. The rate-limiting step is believed to be th e dissolution of the Si from the Ti3SiC2 into the molten Al.
