HIGH PERFORMANCE ALUMINUM NANOCOMPOSITES |
摘要 |
The high performance aluminum nanocomposites are formed by a combination of mechanical alloying and Spark Plasma Sintering (SPS) in order to obtain reinforced nanostrutured aluminum alloys, The nanocomposites are formed from aluminum metal reinforced with silicon carbide (SiC) particulates, wherein the SiC particulates have a particle diameter between about 20 and 40 nm. The nanocomposites are prepared by mixing aluminum-based metal, e.g., Al-7Si-0.3Mg, (Al=92.7%, Si-7% and Mg=0.3%), with SiC nanoparticles in a conventional mill to form a uniformly distributed powder, which is then sintered at a temperature of about 500° C. for a period up to about 20 hours to consolidate the silicon carbide particulates in order to obtain the reinforced aluminum metal-based silicon carbide nanocomposite. |
