Transgranular microcracks

Crevice corrosion tests revealed susceptibility to corrosion attack in the presence of corrosion inhibitors, while in their absence no preferential attack in crevice sites was observed, see, in the presence of commercial inhibitors, did not occur for any tested materials in the absence of corrosion inhibitors, transgranular microcracks were present at the bottom of pits on high austenitic stainless steel. 

The wear mechanisms of ceramics have also been widely discussed and several mechanisms have been suggested, which include microcracking [11], fincture [12,13], tribochemical reactions [13,14], transgranular and intergranular cracking [15] and polishing wear [16].
