[ 1 ] - Study on the strengthening mechanisms and failure modes of the ultra-fine grained tri-modal Al5083-5wt. %B4C-Al2024 and Al5083-5 wt. %B4C-Al5083 composites

In this paper, the influence of Al2024 and Al5083 aluminum alloy coarse grains on mechanical properties and fracture mechanism of Al5083-B4C tri-modal composite has been discussed. Al5083 alloy powders with 5 wt. % of boron carbide were milled for 36 hours and 25 and 50 wt. % of coarse grain (CG) Al2024 and Al5083 powders were added to the milled powders and then hot press under argon atmospher...
