Abstract

The search for an alternative to replace cast iron as train brake shoe material due to its weaknesses has brought AC4B/micro SiC composite as an option. A literature study is conducted to identify the effects of artificial aging temperature variation on the mechanical properties and the microstructure of AC4B/micro SiC. The optimum artificial aging temperature will help the formation of the Mg2Si and Al2Cu precipitates which will have an effect on increasing the mechanical properties of AC4B/micro SiC composite. The ultimate tensile strength shows that there was an increasing trend of UTS until it reaches peak aging prior to decreasing afterward. Artificial aging temperature also affects the material hardness, where the data trend is likely has the peak hardness where the sample exceeds its maximum hardness number, after reaching its peak, the hardness number decreased with increasing temperature. Impact toughness is one of the mechanical properties affected by the artificial aging, one of the factors is the change in grain morphology to a more rounded shape, which will make the impact toughness better. An optimum aging temperature is needed to maximize the impact toughness of the composite. Wear is also affected by variation in artificial aging temperature and in line with the hardness of the material, with increasing temperature to a certain point, the optimum wear resistance will be obtained.
