High Temperature Corrosion Characteristics of Al-Si-Mg Alloy in O2 and H2S/H2 Environments

CORROSION BEHAVIOUR OF Al-Li-Cu-Mg ALLOY 8090-T651

Microstructure and corrosion characteristics of laser-alloyed magnesium alloy AZ91D with Al-Si powder.

Blown-powder laser surface alloying was performed on the magnesium alloy AZ91D with Al-Si alloy powder to improve corrosion resistance. Characterization by scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) and x-ray diffraction (XRD) analysis revealed that intermetallic compounds (IMCs) of Mg2Si, Al12Mg17 and Al3Mg2 were formed in the matrix of α-Mg and Al solid solutions...

Influence of Rolling Temperature on Microstructure and Mechanical Properties of Cryorolled Al-Mg-Si Alloy

An effect of rolling temperature on the mechanical properties and microstructural evolution of an Al-Mg-Si alloy was studied. The material was rolled up to a true strain of ∼0.7 at three different temperatures viz; room temperature, liquid propanol and liquid nitrogen. The liquid nitrogen rolled sample exhibited superior properties with a yield and tensile strength of 332 MPa and 364 MPa, respe...

Macro-Segregation and Microstructural Characteristics in Rheo-Diecasting of a High Strength Al–4.8mass%Si–0.7mass%Mg Alloy

Rheo-diecasting with electro-magnetic stirring has been carried out to investigate macro-segregation and microstructural characteristics of a high strength Al­Si­Mg alloy under various process conditions. The amount of initial heterogeneous nucleation and the degree of temperature uniformity in the slurry are dependent on the superheat of the melt at pouring into the slurry making vessel. The f...

Influence of Temperature on Corrosion Behavior of 2A02 Al Alloy in Marine Atmospheric Environments

The corrosion behavior of 2A02 Al alloy under 4 mg/cm² NaCl deposition at different temperatures (from 30 to 80 °C) has been studied. This corrosion behavior was researched using mass-gain, scanning electron microscopy-SEM, laser scanning confocal microscopy-LSCM, X-ray photoelectron spectroscopy-XPS and other techniques. The results showed and revealed that the corrosion was maximal at 60 °C a...
