Growth model and morphology of Ti3SiC2 grains

A model of the growth and morphology of Ti3SiC2 grains is presented in this work. In the growth of Ti3SiC2 grains, Ti6C octahedron can be recognized a s an integrated growth unit and the linking modes of Ti6C octahedra (such a s sharing planes, edges, or apexes) have strong influence on the growth beh avior and morphology of Ti3SiC2 Some experimental phenomena such as preferr ed orientation of the {1 1 (2) over bar 0} plane in CVD method, and some he xagonal sections in the morphology of the fractured surface can be well int erpreted using our model.
