AISI 1045 Steel, Heat Treatment, Vickers Hardness Test, ASTM E92Abstract
AISI 1045 carbon steel is one of the materials widely used in industry due to its good mechanical properties, which can be further enhanced through heat treatment processes. This study aims to investigate the effect of varying temperatures and holding times on the hardness of AISI 1045 steel during heat treatment. Hardness testing was performed using the Vickers method in accordance with ASTM E92 standards. The temperature variations employed in this research were 800"¯ °C, 850"¯ °C, and 900"¯ °C, while the holding times were varied at 60, 90, and 120 minutes. After heating, the specimens were rapidly cooled (quenching) in water to obtain a hard martensitic structure. The test results showed that heat treatment significantly increased the hardness of AISI 1045 steel, from an initial value of 203.8 HV (without heat treatment) to a maximum of 428.3 HV achieved at 850"¯ °C with a holding time of 60 minutes. Data analysis indicated that temperature had a more dominant influence on the increase in hardness compared to holding time. Based on the findings, the combination of 850"¯ °C and a holding time of 60 minutes is recommended as the optimal parameter for heat treatment to enhance the hardness of AISI 1045 steel, making it more suitable for applications requiring high wear resistance and strength.References
