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...
متن کاملThe Dry Sliding Wear Properties of Nano-Sized TiCp/Al-Cu Composites at Elevated Temperatures
Nano-sized ceramic particle reinforced aluminum composites exhibit excellent room-temperature mechanical properties. However, there is limited research on the dry sliding wear behavior of those composites at elevated temperatures, which should be one of the major concerns on elevated temperature applications. Here the Al-Cu composites reinforced with nano-sized TiCp were fabricated. The dry sli...
متن کاملMicrostructure and Dry-Sliding Wear Behavior of B4C Ceramic Particulate Reinforced Al 5083 Matrix Composite
B4C ceramic particulate–reinforced Al 5083 matrix composite with various B4C content was fabricated successfully via hot-press sintering under Argon atmosphere. B4C particles presented relative high wettability, bonding strength and symmetrical distribution in the Al 5083 matrix. The hardness value, friction coefficient and wear resistance of the composite were higher than those of the Al 5083 ...
متن کاملTHE DEFORMATION BEHAVIOR OF AZ31 MAGNESIUM ALLOY AT ELEVATED TEMPERATURES
AZ31 magnesium alloy is considered as a promising alloy in various applications and industries. Furthermore, to design a proper hot working process (rolling, forging and extrusion), the assessment of hot working behaviour of the alloy is necessary. Accordingly, the hot deformation behaviour of AZ31 alloy was studied through hot compression testing method This was carried out in a wide range of ...
