Studying the fatigue strength of C45 steel material before and after quenching

Abstract

The article presents the results of the fatigue strength study of C45
steel material mandrel type before and after quenching, which was
performed on the experimental machine based on the principle of
two-points bending, experimental results determined the fatigue curve
of C45 steel material before and after quenching will be discussed.
The research results help designers accurately refer the fatigue
strength of C45 steel before and after quenching in applied
mechanical design using this material.
