摘要/Abstract

摘要：

采用搅拌摩擦加工法进行了原位合成Al-Ti金属间化合物颗粒增强铝基复合材料的试验,研究了复合材料的微观组织和精细结构。结果表明,以纯Ti粉和纯铝板为原材料,采用搅拌摩擦加工的方法可以原位合成TiAl3金属间化合物颗粒增强铝基复合材料。在复合材料铝基体上,除了生成的TiAl3金属间化合物外,还存在一些纯Ti颗粒以及纯铝基体上的固溶体。经旋转摩擦挤压后,纯铝基体的晶粒得到细化,尺寸为200nm左右,生成的TiAl3晶粒尺寸约为200~300nm。

Abstract:

Al-Ti intermetallic compound(IMC) particle reinforced aluminum matrix composite was in-situ synthesized by friction stir processing,the microstructure and fine structure of aluminum matrix composite were
studied.The results show that TiAl3 IMC particle reinforced aluminum
matrix composite can be fabricated by friction stir processing method with pure Ti powder and aluminum plate as raw materials.In addition to the generated TiAl3 intermetallic compound,there are also a number of pure Ti particles and solid solution of aluminum matrix on the aluminum base metal.The grains of pure aluminum can be refined by rotational extrusion alloying,and the size of aluminum are about 200nm.The size of a TiAl3 particle is about 200nm to 300nm.

Key words: friction stir processing, in-situ synthesized, intermetallics compound, particle reinforced aluminum matrix composite, microstructure
