Abstract

The composite is a combination of two or more materials that form a bond, which each material has different elements and forms a new material. improve the mechanical properties consisting of three stages: The purpose of this study is as a comparison between the influence of type variations and temperature of cooling media to distribution of hardness and microstructure after and before T6 process of composite material aluminum 6061 is done solution heat treatment at temperature 530 temperature 180 ℃ for 2 hours. brine, and oil SAE 40) 70℃, dan 110℃). From the result of measurement and tes shape and dimensions are irregular hardness increases after the heat treatment process and the value of hardness that exist in the variation of the type and temperature of influenced by the internal condition of the material. that all specimens in the compound candidate (Al, MgO, Si, and O) had a percentage value and the compound formed differently shape and dimension, If the value of MgO percentage is low then the change of shape and dimension has the biggest difference value. While the MgO is high then the change of shape and dimension has the smallest differenc The composite is a combination of two or more materials that form a bond, which each material has different elements and forms a new material. improve the mechanical properties of composite materials is by heat treatment T6 sisting of three stages: 1. Solution treatment, 2. Quenching, 3. Artificial aging. The purpose of this study is as a comparison between the influence of type variations and temperature of cooling media to the change of shape distribution of hardness and microstructure after and before T6 process of composite material aluminum 6061-aluminum oxide by squeeze casting method. In the process of T6 is done solution heat treatment at temperature 530℃ for 2 hours and aging at for 2 hours. Specimen 9 with variations of coolant media type brine, and oil SAE 40) and variations of coolant media temperature (r From the result of measurement and testing conducted show that, shape and dimensions are irregular due to non-uniform cooling rates. hardness increases after the heat treatment process and the value of hardness that exist in the variation of the type and temperature of irregular cooling medi influenced by the internal condition of the material. XRD microstructure testing showed that all specimens in the compound candidate (Al, MgO, Si, and O) had a percentage value and the compound formed differently. But the MgO compound affects changes in If the value of MgO percentage is low then the change of shape and dimension has the biggest difference value. While the MgO is high then the change of shape and dimension has the smallest difference value. The composite is a combination of two or more materials that form a bond, in which each material has different elements and forms a new material. One way to of composite materials is by heat treatment T6 stribution of hardness and microstructure after and before T6 process of composite In the process of T6 for 2 hours and aging at Specimen 9 with variations of coolant media type (water, (room temperature, ting conducted show that, changes in uniform cooling rates. The value of hardness increases after the heat treatment process and the value of hardness that exist in irregular cooling media, because it is XRD microstructure testing showed that all specimens in the compound candidate (Al, MgO, Si, and O) had a percentage the MgO compound affects changes in If the value of MgO percentage is low then the change of shape and dimension has the biggest difference value. While the MgO is high then the change of
