Impact Load Resistance of Steel after Heat Treatment and Quenching with Distilled Water
Journal Title: Engineering and Technology Journal - Year 2024, Vol 9, Issue 12
Abstract
Given that low carbon steels have favourable mechanical properties, they are widely used in power plant components, oil and gas pipelines, and armor structures. However, the relationship between a steel's structure and mechanical properties can occasionally be negatively impacted by the existence of ferrite and pearlite phases in its microstructure. One of the most crucial aspects of engineering metallurgy is the heat treatment of steels, which improves a variety of mechanical and physical characteristics that are useful in many structural applications. The heating and cooling of an alloy or metal while it is solid in order to refine its grain size and other properties and create the necessary microstructures is known as heat treatment. This paper will use distilled water as a cooling medium at various temperatures to perform repeated heat treatments. Comparing the impact load resistance of the original and treated specimens is the goal, as is the impact of multiple heat treatments and the use of distilled water as a medium for cooling at different temperatures. The findings of an Excel program study show that the heat-treated samples had a greater impact resistance value than the untreated ones. The strong martensitic network alloys created by heat treatment procedures are the main factor contributing to the increase in impact load resistance. The average pendulum angle values of the six heat-treated compounds were found to have a higher elevation angle than the average values of the original group. There was the least amount of decrease from the average value of the second group, which was 0.93 %. The average toughness values of the six heat-treated groups increased in comparison to the original group's average values, with the second group experiencing the largest percentage increase (11.96%). Based on the difference in coolant temperatures, the group that was cooled in distilled water at zero temperature had the best toughness value.
