Abstract:

Single-crystal and polycrystalline TiB2 was examined to develop applicable metallographic techniques for sectioning, mounting, grinding, polishing, and etching of TiB2 specimens. This work demonstrates the usability and practicability of using various SiC papers together with different grades of diamond paste on polishing wheels in preference to using cloths. It has been found that H2SO4, as a constituent of etchants, produces more reliable and more consistent results than HF. The same is true of H2SO4 when used as a constitutent of electrolytes. Single-crystal TiB2 was found to have a type of Widmanstatten structure while polycrystalline TiB2 had a needle-like pattern. Author
