On the Faceted and Inclined Twin Boundary of Titanium Carbide Derived from Nanolaminated Ti^sub 3^AlC^sub 2

Due to its high twin boundary energy, the absence of S3...112... in covalently bonded TiC has been theoretically adjudged.

Summary:Due to its high twin boundary energy, the absence of S3...112... in covalently bonded TiC has been theoretically adjudged. Here, we report the observation of TiC twin boundaries that consist of S3...112... and S3...111... steps in a faceted and inclined manner. The twin interface in the transition region is not flat, wherein periodic contrasts resulting from overlapped twins were identified. Based on the microstructural analyses, a formation mechanism for the energy-expensive S3...112... and inclined twin boundaries is elaborated. (ProQuest: ... denotes formulae/symbols omitted.)
