Massive aluminum base noncrystal/nanocrystal composite material and preparation method thereof

The invention belongs to the field of non-crystalline material preparation, particularly relates to a massive aluminum base noncrystal/nanocrystal composite material and a preparation method thereof, and particularly relates to a method for preparing the massive aluminum base noncrystal/nanocrystal composite material by adopting a spray deposition forming method. The massive aluminum base noncrystal/nanocrystal composite material comprises the following components in percentage by weight: 86% of aluminum, 0.5% of silicon, 4.06% of nickel, 2.94% of cobalt, 6% of yttrium and 0.5% of lanthanum and is in a composite structure which comprises a nanocrystal alpha-Al and an amorphous base. The composite material disclosed by the invention is in a noncrystal/nanocrystal composite structure and excellent in mechanical property, breaks through the bottleneck of the preparation size of the composite material in the prior art, can achieve the macroscopic size to 200 mm and is suitable for industrialized application; and the preparation process of the massive aluminum base noncrystal/nanocrystal composite material is simple, convenient to operate and favorable to the industrial popularization.
