AZ91, which is used in the production of parts aerospace, defense and automotive industries, can be enhanced by addition an alloying element or cooling rate, due to weak strength formability properties advanced technology Mg-alloys. The microstructure change Mg alloys significantly affects mechanical properties. By analyzing these alloys, a close estimate made. In this study, image processing-b...

AZ91 magnesium alloy parts were successfully produced using a novel extrusion-based additive manufacturing process. The green built in two different orientations and subjected to debindi...

Lightweight structural materials are increasingly sought after in the automotive and aerospace industries for their potential to improve fuel efficiency. Magnesium-based metal-matrix composites candidates these kinds of applications. The use recycled carbon fibres offers further energy cost savings. fibre were manufactured by stir casting with high-dispersion shearing, then extruded subsequentl...

In this study, the deformable titanium (Ti) particles reinforced AZ91 composite was successfully prepared by powder metallurgy and subsequent extrusion. The mechanical properties microstructural evolution of pure 5Ti/AZ91 were studied. yield strength, ultimate tensile elongation are measured to be 212 MPa, 323 10.1%, respectively. Microstructure analysis revealed that Ti elongated along extrusi...

Surface nanocrystallization using a surface mechanical attrition treatment effectively activates the surface of magnesium alloys due to the increase in grain boundary diffusion channels. As a result, the temperature of subsequent surface alloying treatment of pure Mg and AZ91 alloy can be reduced from 430 degrees C to 380 degrees C. Thus, it is possible to combine the surface alloying process w...

The use of magnesium alloys is limited due to their susceptibility to corrosion although they have many attractive physical and mechanical properties. To increase mechanical and corrosion properties of these alloys, many deposition method and coating types are used. Electroless Ni–B coatings have received considerable interest recently due to its unique properties such as cost-effectiveness, th...

This paper deals with the study of crystallization and phase transformation Ni-P coatings deposited on AZ91 magnesium alloy. Prepared samples were characterized in terms surface morphology elemental composition by means scanning electron microscopy energy-dispersive spectroscopy analysis. The results X-ray diffraction analysis differential calorimetry suggested that increasing phosphorus conten...
