A Study of the Structure, Mechanical Properties and Corrosion Resistance of Magnesium Alloy WE43 After Rotary Swaging

The structure and properties of magnesium alloy WE43 are studied after homogenizing and rotary swaging deformation conducted in several stages with step lowering of the temperature from 400 to 325°C and increasing the extrusion ratio to 2.56 – 2.78. The deformation yields an ultrafine-grained (UFG)...

Description
Summary:The structure and properties of magnesium alloy WE43 are studied after homogenizing and rotary swaging deformation conducted in several stages with step lowering of the temperature from 400 to 325°C and increasing the extrusion ratio to 2.56 – 2.78. The deformation yields an ultrafine-grained (UFG) structure with a mean size of the structural components about 500 – 800 nm and particles of aMg 41 Nd 5 phase with a mean size of about 300 – 400 nm. The formation of the UFG structure raises the strength of the alloy. The best combination of mechanical properties is provided by swaging with the final temperature 325°C. It is shown that the rotary swaging deformation does not affect the corrosion rate of the alloy measured by the methods of potentiodynamic polarization, loss in the mass and emission of hydrogen.
