Embrittlement of Al-Li-Cu-Mg alloys at slightly elevated temperatures: microstructural mechanisms of hardening
When underaged, damage tolerant Al-Li based alloys are exposed to slightly elevated temperatures (60 to 100oC), their strength increases and toughness decreases. To study the first stages of this process, 8090 sheet in three underaged heat treatment conditions, including T3, T81 and a multistage temper, was exposed for 1000 h at 70°C. Using a model for strengthening in combination with a quanti...
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 ...
متن کاملMicrostructural Evolution of Roll Bonded Al-Clad Stainless Steel Sheets at Elevated Temperatures
The cold roll bonding of Al on AISI 304L stainless steel was carried out to fabricate the Al/304L/Al clad sheet composites. The maximum bond strength of 20 N/mm was acquired just by 38% reduction, for which the tearing of the aluminum sheet occurred during the peeling test. The microstructural evolution during subsequent postannealing heat treatment was systematically studied based on the impur...
متن کاملInteraction of oxygen with Al„111... at elevated temperatures
The interaction of oxygen with Al~111! was investigated by STM at temperatures between 350 and 530 K, by annealing an oxygen precovered surface and by adsorption of oxygen on the hot surface. For exposures up to 10 L and temperatures up to 470 K a considerable part of the oxygen exists still in the chemisorbed state, another part transforms into Al oxide. In contrast to 300 K chemisorbed Oad at...
متن کاملEnhanced Compressive Property of Al Composite Foams at Elevated Temperatures via Plasma Electrolytic Oxidation
The present work investigates the compressive property of Al matrix composite foams at different temperatures between room temperature and 200 ◦C. Elevated temperature results in a decreased compressive strength and energy absorption capacity of as-received Al foams. Therefore, to maintain the compressive property, the Al2O3 ceramic coating was deposited on the Al struts of the foams by the pla...
