Crystallography of directionally solidified magnesium alloy AZ91
Metallurgical Transactions A, 1989The crystallographic direction of growth in directionally solidified magnesium alloy AZ91 has been studied by TEM and EBSP techniques in SEM. The main direction of growth is found to be $$\left\langle {11\bar 20} \right\rangle $$ .

Characterisation of TG-SCC In Pure Magnesium and AZ91 Alloy
2008Our recent critical review of the stress corrosion cracking (SCC) of magnesium aims to provide a foundation for the safe and effective use of magnesium alloys, including practical guidelines for the service use of Mg alloys in the atmosphere and/or in contact with aqueous solutions.

Two-Step Anodization of AZ91 Magnesium Alloy
Materials Science Forum, 2005Among four AZ91 samples, two were once anodized and the others were twice anodized in two electrolytic baths. After twice anodization, two coatings coexist on the base metal. Surface morphology showed that for one of twice anodic coatings (sample 2), the second coating only existed on some places and sealed some pores of the first coating after short ...

Study on the fluidity of AZ91+xRE magnesium alloy
Materials Science and Engineering: A, 1999Influence of section thickness, pouring temperature, mould temperature and content of rare earth (RE) element on the fluidity of AZ91 magnesium alloy has been studied through fluidity specimens with different section thickness cast in metal mould. The results show that the relation curve of filling length versus section thickness can be divided into ...

Study on the Filtering Purification of AZ91 Magnesium Alloy
Materials Science Forum, 2009High quality magnesium casting depends significantly on the purification of its alloy melt. However, it is very difficult to obtain high-quality magnesium alloy melt due to its high reactivity and its tendency of combustion. The fluxing processing, a traditional purification method for magnesium melt, not only bears the risk of flux inclusions but also

Nickel Foam Reinforced AZ91 Magnesium Alloy
Materials Science Forum, 2007Nickel foam reinforced AZ91 magnesium alloy was fabricated by using melt infiltration and water quenching methods. The mechanical properties were measured in compressive and tensile deformation modes. Fracture surfaces were examined by scanning electronic microscopy.

Mechanical spectroscopy of commercial AZ91 magnesium alloy
Scripta Materialia, 2001Abstract A damping peak at around 425 K for a frequency of about 1 Hz was found and it was correlated to the characteristic grain boundary peak of magnesium. An increase in the height of the grain boundary peak appears during the temperature cycles, controlled by the decrease of solute atoms in the matrix since the appearance of a precipitation ...

Thermal Fatigue of Magnesium Base Alloy AZ91*
Materials Testing, 2009Abstract Thermal fatigue tests of the magnesium-base alloy AZ91 were carried out under total strain control and out-of-phase-Ioading conditions in a temperature range between 50°C and +190°C. Specimen produced by a vacuum die casting process were loaded under constant total strain and uniaxial homogeneous stress.

Fatigue of AZ91E-T6 Cast Magnesium Alloy
Journal of Engineering Materials and Technology, 1993The purpose of this research was to obtain room temperature fatigue behavior of AZ91E-T6 cast magnesium alloy and to determine if commonly used models that depict fatigue behavior are applicable to this cast alloy. Axial strain-controlled fatigue behavior using cylindrical specimens were employed to determine low cycle fatigue behavior with strain ...

Investigation on the yield behavior of AZ91 magnesium alloy
Journal of Alloys and Compounds, 2018Abstract In this paper, quasi-static compression, tension, shear and combined compression-shear tests are conducted on cast AZ91 magnesium alloy in order to study its yield behavior. For the combined compression-shear tests, shear-compression specimens (SCS) are employed to generate the additional shear stresses, instead of complex loading device ...
