Abstract The present investigation evaluates the effect of milling time, sintering time (t) and temperature (T), and amount of reinforcement (R) on the relative density (RD), hardness (H) and compressive strength (CS) of aluminium matrix hybrid composites both experimentally as well as statistically using response surface methodology (RSM). The powders were milled for various times, i.e., 0.5, 2, 4, 6, 8, 10, 12 &14 h and 10 h milled powder exhibited the desired microstructure. Subsequently, the 10 h milled powders were sintered at 550, 600 & 650 °C for 1 h. The 10 h milled powders were also sintered for various times, i.e., 1, 1.5 & 2 h at 600 °C temperature. The maximum values of RD, H and CS are obtained when the 10 h milled powders are sintered at 600 °C for 1 h. The RSM technique successfully correlates the T, t and R with RD, H and CS.

评估球磨时间、烧结温度和时间对 Al-Y2W3O12-AlN 杂化复合材料微观结构变化和力学性能的影响

摘要 本研究评估了铣削时间、烧结时间 (t) 和温度 (T) 以及增强量 (R) 对铝基体的相对密度 (RD)、硬度 (H) 和抗压强度 (CS) 的影响。使用响应面方法 (RSM) 在实验和统计上混合复合材料。粉末被研磨不同时间，即0.5、2、4、6、8、10、12和14小时和10小时研磨的粉末表现出所需的微观结构。随后，将 10 小时研磨的粉末在 550、600 和 650 °C 下烧结 1 小时。10 小时研磨的粉末也在600°C 的温度下烧结不同的时间，即1、1.5 和2 小时。RD、H 和 CS 的最大值是在 10 小时研磨后的粉末在 600 °C 下烧结 1 小时时获得的。RSM 技术成功地将 T、t 和 R 与 RD 相关联，
