Microstructures and Properties of Laser Al Alloying on AZ31 Magnesium Alloy

Advanced Materials Research, 2011
In order to improve corrosion and wear resistance of magnesium alloy, Al coating was prepared on the AZ31 magnesium alloy by the thermal spraying, then the Al-rich layer was obtained by using a CO2 laser re-melting. The microstructures and phases of the alloying layer were analyzed by canning electron microscope (SEM) and X-ray diffraction apparatus ...

Strain-hardening behaviour of AZ31 magnesium alloys

International Journal of Materials Research, 2009
Abstract The in-plane tensile behaviour of rolled sheets of the magnesium alloy AZ31 was investigated in both an H24 state and an aged state. Whereas the very high initial strain-hardening rate decreases monotonically with strain for the H24 samples, the annealed structure exhibits a striking increase in the strain-hardening rate.

Tube extrusion of AZ31 alloy with Sr additions

Materials Science and Engineering: A, 2012
Abstract Three Mg alloys (AZ31, and AZ31 + 0.4 and 0.8 wt%Sr) were successfully hot extruded into tubes at 400 °C through a porthole die. Strontium (Sr) additions to AZ31 alloy reduced twining and the dynamically recrystallized grain size. However, Sr also increased the surface cracking tendency during extrusion.

ACCUMULATIVE ROLL BONDING OF AZ31 MAGNESIUM ALLOY

International Journal of Modern Physics B, 2008
This work conducted to investigate the effects of accumulative roll bonding (ARB) method on achieving the ultra-fine grain microstructure in AZ31 alloy. Accordingly, a number of ARB routes at 400°C, applying thickness reductions per pass of 35%, 55%, and 85% were performed.

Electrodeposition of copper coating on AZ31 magnesium alloy

Surface Engineering, 2012
Magnesium and its alloys have limited wide applications due to their poor corrosion resistance. In this study, copper coating used as a plating nickel substrate was directly electrodeposited on AZ31 magnesium alloy from copper hydroxide and citrate bath with the addition of fluorine ion and additives using direct current.

PROTECTIVE TREATMENTS FOR AZ31 Mg ALLOY

2006
The protective performances of different coatings for AZ31 Mg alloy have been evaluated in 0.1N NaCl and Na2SO4 solutions by recording the polarization curves and by EIS measurements. These coatings were formed in permanganate-phosphate or stannate baths as well as in hydroalcoholic solutions of silanes with a long alkyl-chain (e.g. octyl and octadecyl-
