Abstract
Provided are an amorphous alloy-reinforced and toughened aluminum matrix composite (AMC) and a preparation method thereof. The amorphous alloy-reinforced and toughened AMC includes 55 vol. % to 95 vol. % of an aluminum-based alloy and 5 vol. % to 45 vol. % of an amorphous alloy, wherein the amorphous alloy is Fe52Cr26Mo18B2C12.
Claims8
A method for preparing an amorphous alloy-reinforced and toughened aluminum matrix composite (AMC), comprising the following steps:
- (1) mixing a powder of an aluminum-based alloy with an amorphous alloy to obtain a third mixed powder;
- and
- (2) subjecting the third mixed powder obtained in step (1) to continuous extrusion and heat treatment sequentially to obtain the amorphous alloy-reinforced and toughened AMC,
- wherein the amorphous alloy-reinforced and toughened AMC comprises 55 vol. % to 95 vol. % of an aluminum-based alloy and 5 vol. % to 45 vol. % of an amorphous alloy, wherein the amorphous alloy is Fe52Cr26Mo18B2C12.
