Basic understanding of ductile fracture and brittle fracture
At the microscopic level, ductile fracture is characterized by a dimple structure (Fig.). 1a): The micropores caused by inclusions or coarse precipitates are enlarged, and the material between them is necked and sheared during further production. The depth of these depressions can be considered a measure of the ductility of the metal.

Fasteners in the repair process will encounter what problems
Although the fastener is a small part, it is an indispensable part of mechanical equipment and plays a very important role. Therefore, when we use fasteners, we need to carry out regular maintenance, so as to ensure that the use of fasteners is safer, extend the service life of fasteners, and improve the performance of mechanical equipment.
