Optical light metallography and scanning electron microscopy with energy dispersive spectroscopy were used to describe the microstructure and mechanical strength was assessed by microstructure measurements. The chemical analysis confirmed that the shaft is made of AISI 4140 steel according to the specifications. However, microstructural characteristics and microstructure measurements showed that the shaft was improperly subjected to heat treatment, resulting in a brittle case, in which crack propagation occurs in an intergranular state relative to shear within the core. This behavior was related to differences in microstructure, R c 58, and a mixture of perlite and ferrite inside the core with R c 25. It is not possible to reconstruct the exact sequence of events leading to fracture, it may be added by A large load inside the brittle started very hard, which could lead to the car overturning and the final fracture due to the overturning collision. However, the onset of cracking cannot be ruled out due to hydrogen produced by rust and water, as well as the possibility that vehicle overturning was the cause of the fracture.
