Abstract:
The SAE/AISI 1045 steel is one of the structural steels widely used in the automotive sector to several key components such as connecting shafts, axles etc. It is also used in petrochemicals and power generation units. In material science and engineering; four interdependent parameters are of paramount importance which includes; process structure, properties and performance. Among all factors the structure / microstructure is of utmost importance since it governs the properties at large. For example it depends on the size, shape, and distribution of various micro constituents therein. Therefore, the main aim of this study is to investigate the response of the microstructures (structure-property correlation) upon application of heat treatment processes such as annealing, normalizing, tempering and hardening. This was followed by the characterization such as spectrometry analysis was carried out for chemical composition of the steel. While impact and hardness tests were also conducted. Results suggest an improved toughness and hardness when tempering temperature was reduced. This is attributed to decreased grain sizes of micro constituents upon such treatment. Interestingly one more aspect was noted that the chemical composition changes slightly during heat treatment processes which might be in range of standard. However, it could affect the surface properties of steel during service.
