This paper examines the structure and properties of worn mid-motor blades on heavy-duty motor graders operating in Yakutia. The wear characteristics of mid-motor blades at low temperatures are revealed, and operational data are analyzed. The chemical composition, structure, and properties of motor grader blades from two different manufacturers were analyzed. The results showed that the working parts of heavy road construction equipment are characterized by the presence of a finely dispersed, needle-like structural component, which undergoes appropriate heat treatment.
