Abstract:
In order to evaluate the fundamental properties of engineering materials the use of mechanical testing
techniques frequently play a crucial role. The development of new materials and the control of material
quality are essential in the process of design and in their usage for industrial applications and
construction. In this paper, 10 sample steel specimens S45C (M) of 0.45% carbon content were prepared
according to ASTM standards with selected varied parameters such as machining cutter speeds,
mediums and temperatures of quenching and subjected to aggregated tensile loads. The consequential
effect of material structure metamorphosis under the selected quenching techniques was not part of the
study as it involves microscopic analysis of grain boundaries. The results suggest that the macroscopic
effect of machining speeds do not significantly affect the tensile material strength of the material. Thus,
focus on the mediums and temperatures selected in the quenching process itself do contribute marginally
to the elevated levels of tensile strength and strain in the sample material.
