Generally properties of as-cast AZ91 soft Mg-alloy can be improved by conventional artificial aging. Conventional methods are time consuming and expensive process. Friction stir processing (FSP) based on working principle welding replace the processes at some extent. FSP generates enough heat in process to decrease grain size coarse grains significantly accordingly alter properties. extensive u...

In the presented work, possibility of direct synthesis LDH (layered double hydroxide) on AZ91 surface in presence a chelating agent (diethylenetriaminepentaacetic acid - DTPA) is reported. Conversion layer nanocontainers were formed under ambient pressure conditions without carbonate addition electrolyte. The obtained was characterized using experimental (SEM, XRD, TGA, XPS, Raman, etc.) and co...

in this study, the effects of forming method (extrusion) and environmental factors (solution ph and temperature) on the corrosion performance of az91 magnesium alloys were investigated using potentiodynamic polarization, electrochemical impedance spectroscopy (eis), scanning electron microscopy (sem) and salt spray techniques. the polarization test results of the specimens showed that simple sh...

The crystallography and kinetics of Al 11 Mn 4 formation on 8 5 have been studied in magnesium alloys AZ80 / AZ91 AZ31. During solidification, was promoted by low cooling rates where triclinic nucleated rhombohedral particles with one multiple related orientation relationships (ORs) their variants. grew as (010) plates that were commonly twinned the interrelationships amongst twins, twins -Al O...

In this work, magnesium-based composites were obtained by shock-wave compaction of a powder mixture Mg-5 wt.% AlN at pressure 2 GPa. Their microstructure was investigated and the phase composition determined, from which it follows that nanoparticles retain their are uniformly distributed in magnesium matrix. The materials used as master alloys for production die casting. amount aluminum nitride...
