Anticorrosive magnesium phosphate coating on AZ31 magnesium alloy

Surface and Coatings Technology, 2009
A novel anticorrosive film with a thickness of approximately 50 μm was successfully coated on an AZ31 magnesium alloy by chemical and low-heat treatments (50 °C). The film was a single-phase system of newberyite (MgHPO 4 •3H 2 O) having an orthorhombic crystal structure.

Hot Rolling of AZ31 Magnesium Alloy to Sheet Gauge

SAE Technical Paper Series, 2006
<div class="htmlview paragraph">This study details preliminary results of hot rolling trials of AZ31 alloy sheet using a pilot-scale rolling mill. The aim is to design and optimize the hot rolling schedule for AZ31 in order to produce sheet with a fine and homogeneous microstructure.

Deformation Mechanisms of AZ31 Magnesium alloy

2016
A detailed investigation of the deformation mechanisms plays an important role for a better understanding of texture evolution and anisotropic behavior of magnesium wrought alloys. Therefore, room temperature deformation tests of AZ31 hot rolled sheets and extruded bars have been performed.

An Investigation of TIG Welding of AZ31 Magnesium Alloy Sheets*

Materials Testing, 2014
Abstract In this study, butt welding of commercial AZ31 magnesium alloy sheets has been investigated by using the tungsten inert gas welding process with alternating and pulsed current. Magnesium alloy welding, although well developed and understood, can present some problems, such as porosity, hot cracking, oxide formation, etc. Samples

Investigation of Flow-Formability of an AZ31 Magnesium Alloy

Transactions of the Indian Institute of Metals, 2020
Flow-formability of a Ca-added AZ31 magnesium alloy tube is investigated. The flow-forming process is conducted at various temperatures (100–500 °C), thickness reductions (30–85%), and feed rates (0.1–0.56 mm/rev). Inner and outer surfaces of the tubes are heated by means of a thermal element embedded inside the mandrel and a radiation element ...

Numerical-Experimental Characterization of a Superplastic AZ31 Magnesium Alloy

Materials Science Forum, 2007
In this work the superplastic behaviour of a hot rolled AZ31 magnesium alloy sheet under a biaxial tension test with the blow forming technique is presented and reported. The specimen dome height and its thickness distribution, during and after the test, have been used as characterizing parameters. A numerical FE model of the test has been developed in

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.

Developing superplasticity in a magnesium AZ31 alloy by ECAP

Journal of Materials Science, 2008
The processing of a magnesium AZ31 alloy by equal-channel angular pressing refines the grain size to ~2.2 μm, but annealing for 30 min at 673 K coarsens the grains to ~6.0 μm. Despite this microstructural instability, the alloy is superplastic when pulled in tension at temperatures in the range of 623–723 K with elongations up to >1000% at strain rates

Modelling of Superplastic Forming of AZ31 Magnesium Alloy

AIP Conference Proceedings, 2011
In this study the constitutive equation of the superplastic AZ31 magnesium‐based alloy is modelled by the power law relationship between the stress, the strain and the strain‐rate and an accurate procedure for determining the constants of the material is presented.
