О металловедческом исследовании при производстве автотехнической экспертизы

Abstract

Quite often, traffic accidents occur due to a sudden failure of the steering, undercarriage or brake system of a car associated with the technical condition of vehicles. In this case, various parts of vehicles (steering, springs, wheels, couplers and braking system, etc.) are destroyed. However, destruction of these parts can also occur as a result of traffic accidents, for example, in a collision or rollover. Therefore, in cases of road accidents, an auto-technical examination is appointed. It is important for making an informed and objective decision on the case to clarify the reasons for the destruction of parts that affect the safety of the vehicle, and the establishment of the time for the occurrence of these malfunctions. Conducting a metallographic expertise, which in most cases is auxiliary, can significantly help the investigation and the court, when solving these issues. Its conclusions are supplemented and specified by the conclusions of another examination, for example, auto-technical. The paper outlines the scheme and stages of research of products made of metals and alloys performed by experts in the production of automotive expertise to establish a causal relationship between the technical condition of the vehicle and the mechanism of traffic accidents.
