高压原位合成Al_3Ni晶须增强Al基复合材料

In Situ Synthesis of Al_3Ni Whiskers Reinforced Al Matrix Composites U nder High Pressure

在 1～ 6 GPa高压范围内原位合成 Al3Ni晶须增强 Al基复合材料。原位合成的 Al3Ni晶须尺寸小 ,在高致密度的复合材料中分布弥散 ;并研究了高压对 Al3Ni晶须尺寸及晶须分布取向的影响。

The Al3Ni whiskers reinforced Al matrix composites were successfully in situ synthesized under high pressure within1～ 6GPa.The sizes of Al3Ni whiskers are fine,and uni- formly distributed in these densified composites.The influence of high pressure on the size and structure of Al3Ni whiskers are disccused.
