Here, we present a case of brittle fracture, which is a type of destruction. Upon further microscopic observation (using an electron microscope) of the fracture surface, features that were not apparent in macroscopic observation (visual inspection) became clear. From the microscopic observation images magnified approximately 1000 times, the fracture surface of the metal component displayed characteristics of cleavage fracture and suspected cleavage fracture. These are characteristic fracture surfaces observed in brittle fractures, allowing us to conclude that this metal component was fractured in a brittle manner. 【Case Summary】 ■ Features that were not apparent in macroscopic observation became clear ■ Shapes of cleavage fracture and suspected cleavage fracture were observed ■ It was determined that the fracture occurred in a brittle manner *For more details, please download the PDF or feel free to contact us.

Here is an example of fatigue failure, which is a type of fracture. From several microphotographs taken at tens of times magnification, multiple ratchet marks (steps generated by the merging of fatigue fracture surfaces) were observed near the fracture initiation point. Additionally, at approximately 1000 times magnification, striations (fatigue wrinkles) were seen as wave patterns. These characteristic patterns observed in fatigue failure were noted on the fractured surface of this metal component, allowing us to conclude that this metal part failed due to fatigue. [Case Summary] - Features not discernible through macro observation (visual inspection) were revealed. - Ratchet marks and wave patterns known as striations were observed. - It was determined that the failure was due to fatigue. *For more details, please download the PDF or feel free to contact us.
