Investigation of metal parts damage incidents
It is possible to investigate the cause of metal parts damage accidents.
When metallic materials fail, the mode of failure changes due to various factors such as the properties of the material, applied stress, and environmental conditions. By observing the fracture surface in detail using an electron microscope, it is possible to identify the cause of the failure to some extent from the fracture morphology. Failure modes can be broadly classified into four categories: ductile fracture, brittle fracture, fatigue fracture, and environmental fracture. Ductile fracture involves significant deformation, such as elongation, before failure occurs. Brittle fracture is characterized by crack propagation at a high speed without plastic deformation. Fatigue fracture occurs when cracks gradually propagate due to repeated stress. Environmental fracture is a failure that is significantly accelerated by corrosive environments, leading to rapid crack propagation.
