Magnesium alloys are attracting great interest from the automotive industry because of the potential for weight reduction. An AZ91D cast alloy was studied in the current work to understand the effect of heat treatment on the microstructure and dynamic compressive properties. The selected heat treatments include solution treatment (T4) and solution treatment followed by aging (T6). The as-cast a...

Effects of constant temperature and humidity testing on the adhesive properties phosphate-anodized AZ91D magnesium alloy were evaluated to produce multiple materials for lightening fabrication these materials. Phosphate-anodized alloy, after immersion in dilute nitric acid solution, maintained strong strength even testing. These findings suggest that anodization film is bonded chemically by sol...

Aluminum coating was prepared on AZ91D magnesium alloy substrate using the electrophoretic deposition (EPD) method in absolute ethanol solvent. In order to determine the optimal concentration of AlCl3.6H2O additive, the zeta potential and size of particles in the suspension were measured in the presence of different concentrations of AlCl3.6H2O. The results showed that an appropriate coating is...

Considerable research has been carried out to study the laser welding of magnesium alloys. However, studies are mainly devoted butt welding, and there limited information in published literature concerning bead-on-plate AZ91D, even though is required for repair cast AZ91D parts with surface defects. In present investigation, cracking weld metal was observed when an alloy welded using method. Th...

Stress Corrosion Cracking (SCC) of magnesium alloys is commonly observed in corrosve environments such as NaCl solutions. In this paper, the effect aluminum content on SCC alloy ingots, AM60B and AZ91D, evaluated using Slow Strain Rate Testing (SSRT) two environments: (1) air (2) 5%NaCl solution controlled from pH10 to pH11 with Mg (OH）2. The result shows that less susceptible than AZ91D. AZ91D...
