Over the years, aluminum content in a vehicle part is increasing due to the needs to reduce weight as well as increase fuel efficiency. Most of the cast product in a vehicle part is mostly cast from A356 alloy. It is used because A356 alloy posses’excellent characteristics over other type of alloy such as cast ability, high weight-to-strength ratio, good corrosion resistance and good weld-abili...

A method coupling experiments and simulations, is developed to characterize the yield stress strain hardening of several metals loaded at 106 s?1 < 25 ns, typically involved during Laser Shock Peening. It was applied four materials: pure aluminum, 2024-T3 7175-T7351 aluminum alloys Ti6Al4V-ELI titanium alloy. Thin foils have been irradiated with high-power laser induce high-pressure shock wave....

Values of release wave speed in shock-compressed polycrystalline alumina and aluminum (2024) have been measured to 400 and 260 kbar, respectively. These values, as well as previous data for aluminum and iron, have been compared with fourth-order finite strain extrapolations of the longitudinal sound speed V o. For alumina in the pressure range 200-300 kbar and for a iron and • iron the observed...

the synthesis of polyaniline- fe2o3 nanocomposite coating on aluminum alloy 5052 (aa5052) surface has been investigated by using the galvanostatic method. the anticorrosion performance of polyaniline-fe2o3 coating was investigated in 3.5% nacl solution by the open- circuit potential (ocp), tafel polarization technique and electrochemical impedance spectroscopy (eis). the corrosion rate of polya...

the direct synthesis of polyaniline-tio2 nanocomposite coatings on aluminum alloy 3004 (aa3004) surface has been investigated by using the galvanostatic method. the synthesized coatings were characterized by ft-ir, sem-edx, sem and afm. optical absorption spectroscopy reveals the formation of the emeraldine oxidation state form of polyaniline-tio2 nanocomposite. the corrosion performances of po...
