【摘要】 利用固液反应球磨技术,采用Fe球球磨液态Al Cu和Al Si二元合金熔体,制备了Al Cu Fe与Al Si Fe系三元合金,研究了Al Cu Fe和Al Si Fe三元合金相形成规律。在923K球磨液态的Al 33.2%Cu共晶合金,球磨48h后,得到Al13Cu4Fe3的固相粉末;在943K球磨Al 54%Cu(Al2Cu)合金熔体,球磨24h后,Al2Cu的液相消失,得到了固相的Al65Cu20Fe15和Al13Cu4Fe3混合粉末;在963K球磨Al 7%Si亚共晶合金熔体,球磨48h后,Al Si液相消失,得到固态的Al8Fe2Si合金粉末;在963K球磨Al 12.6%Si共晶合金熔体,球磨48h后,Al Si的液相消失,得到固态的Al8Fe2Si粉末;在1133K球磨Al 30%Si过共晶合金熔体,球磨24h后,Al Si的液相消失,得到固态的Al3FeSi合金粉末。在上述球磨中,若加入一定量的Fe粉,将加速反应进程。固液反应球磨产物是在打击剥离的过程中制得的。更多还原

【Abstract】 Al-Cu and Al-Si binary alloy melt were milled by Fe ball to fabricate Al-Cu-Fe and Al-Si-Fe ternary alloy powders by using a novel solid-liquid reaction milling technology. In comparison with that of high-energy ball milling, the phase formation rule of ternary alloys of the newly developed technology was studied. Al₁₃Cu₄Fe₃ powder was obtained by milling Al-33.2% Cu eutectic alloy melt at 923 K after 48 h. Al₂Cu disappeared and Al₆₅Cu₂₀Fe₁₅ and Al₁₃Cu₄Fe₃ powder were prepared when Al-54%Cu（Al₂Cu） alloy melt was milled at 943 K after 24 h. Al₈Fe₂Si powder was obtained by milling Al-7%Si（mass friction） hyporeutectic alloy melt at 963 K after 48 h. Al₈Fe₂Si powder and Al₃FeSi powder was formed by milling Al-12.6%Si eutectic alloy melt at 963 K after 48 h and Al-30%Si hypereutectic alloy melt at 1 133 K after 24 h, respectively. Moreover, the reaction is the process of striking and stripping.更多还原
