| 摘 要： | 研究了Cu-Al-TiO2-B2O3粉末在机械合金化和随后的烧结过程中结构的变化，结果表明：Cu-Al-TiO2-B2O3粉末通过机械合金化可以形成Cu(Ti,B）及Al2O3和少量的TiCu3粉末，Al2O3是通过机械合金化过程中的自维持反应形成的，采用Cu,Al,TiO2和B2O3作为原料，通过机械合金化和随后的加压烧结，可以制备性能较好的（TiB2 Al2O3）增强铜基复合材料。 |
| 关 键 词： | TiB2 Al2O3 铜基复合材料 铜合金 机械合金化 自维持反应 硼化钛 氧化铝 粉末增强 |

| Abstract: | The structure changes of Cu Al TiO 2 B 2O 3 powders during mechanical alloying and sintering subsequently were investigated The results indicate that Cu(B, Ti), Al 2O 3 and a little TiCu 3 powders can be formed in Cu Al TiO 2 B 2O 3 powders through mechanical alloying, the Al 2O 3 is formed by a local self sustained reaction during mechanical alloying The dual phase reinforced composite Cu (TiB 2+Al 2O 3 ), with a good properties, can be synthesized through processes of mechanical alloying and sintering with the raw materials of Cu, Al, TiO 2, and B 2O 3 |
| Keywords: | composite copper alloy mechanical alloying self sustaining reaction |
