Al6061-sea sand composite was manufactured using the stir casting method and its mechanical properties were improved by heat treatment. The T6 heat treatment used to improve the mechanical properties of the composite consists of the following processes: solution heat treatment, quenching, and artificial aging. The solution heat treatment process was carried out at a temperature of 540 o C for 6 hours. The quenching process was carried out with different quenching agents (water, oil, and 10% brine). The difference in quenching agents resulted in different cooling rates. After quenching, an artificial aging process was carried out at a temperature of 200 o C for 4 hours. The difference in cooling rate affects the hardness and tensile strength of the specimen. The high cooling rate results in an increase in the tensile strength of the specimen. This is due to the increase in cooling speed, the Mg 2 Si precipitates formed are smaller in size and located in the grains. The highest tensile strength of specimen (206.67 MPa) is obtained by using brine quenching agent.

“…Additionally, Cu addition has been found to have an impact on the diffusion of alloying elements and variant selection. This effect leads to a reduction in element segregation at grain boundaries, thereby inhibiting the coarsening of grains in the heat-affected zone of welded joints [ 18 , 23 , 24 ].…”

This paper presents a comprehensive study of the impact of quenching roll speed on enhancing the low-temperature toughness of a low-carbon copper-containing steel. The microstructure characteristics, such as the prior austenite grains, and the distribution and volume fraction of precipitates, are observed using optical microscopy, scanning electron microscopy, transmission electron microscopy, and small-angle scattering X-ray. The results show that a decrease in the quenching roller speed (2 m/min) contributes to the achievement of more excellent low-temperature toughness (the average value is 232 J), although the prior austenite grains exhibit a relatively larger size in this case. The tempering treatment results in the precipitation of a large amount of 9R-type Cu-rich particles, regardless of the quenching roller speed. Reducing the quenching roller speed contributes to the increase in the volume fraction of Cu-rich particles, which is considered to be the main factor contributing to the achievement of excellent low-temperature toughness.
