Abstract

The deformation process will result in an increase in metal strength that will occur depending on how much deformation or strain will be received by the workpiece. The objective of this study is to determine the effect of temperature variations of 150oC, 160oC, 170oC and reduction of cross section 5%, 10%, 15% in the forging process and before the forging process on Al 2xxx composites (used piston) coal bottom-ash alloys on the wear rate and microstructure. The wear test results can be seen that the temperature variation and cross section reduction greatly affect the wear resistance with the lowest wear rate in specimens with 170oC temperature variations and 15% cross section reduction with the result of 0.004 x 10-6 mm3/mm, for the microstructure making the grain size increasingly small ie with the lowest average grain size in specimens with a temperature variation of 170oC and a reduction of 15% cross section with a result of 133.3 µm inversely proportional to before the forging process where the wear resistance is very low with a wear rate value on the specimen is very high with a result of 0.054 x 10-6 mm3/mm and the microstructure makes a grain size with a yield of 257.56 µm. This shows that the greater the temperature and reduction of the cross section in the forging process of aluminum 2xxx (used piston) coal bottom ash alloy can improve its mechanical properties.
