Influence of Forging Process Parameters on Graphene Reinforced Aluminum Matrix Composites for Automobile

采用不同的锻造工艺参数对新型铝基复合材料进行了锻造试验,并对冲击、磨损性能进行了测试与分析。结果表明:随始锻温度、终锻温度和锻造比的增加,试样的冲击吸收功先增大后减小、磨损体积先减小后增大;在470℃始锻与350℃终锻时,锻造比12的试样的冲击吸收功最大,磨损体积最小。汽车用新型铝基复合材料的锻造工艺参数优选为:470℃始锻温度、350℃终锻温度、锻造比12。

The forging test of a new type of aluminum matrix composites was carried out by using different forging process parameters. The impact and wear properties were tested and analyzed. The results show that with the increase of the initial forging temperature, the final forging temperature and the forging ratio, the impact absorption work of the samples increases first and then decreases, and the wear volume decreases first and then increases. The impact absorbing work of the samples with the forging ratio of 12 is the largest and the wear volume is the smallest at initial forging temperature of 470℃and the final forging of 350℃. The optimum forging process parameters of new aluminum matrix composites for automobile are initial forging temperature of 470 ℃, final forging temperature of 350 ℃ and forging ratio of 12.
