“…As in many metallic alloys, their room-temperature mechanical properties and superplasticity can be greatly improved through grain refinement. Ultrafine grain (UFG) Mg alloys with grain sizes of 0.5-5 m have been obtained by equal channel angular pressing (ECAP) [1][2][3] and accumulative rolling bonding (ARB) [4] and large strain hot rolling (LSHR) [5]. Recently, a novel rolling method of fabricating Mg sheets with high strength and high ductility was proposed [6].…”

“…This assumption is particularly supported by high deformation energy stored in larger grains. RDX very probably may also contribute to the joining of sheets during the ARB process [ 27 ].…”

Deformation behaviour of rolled AZ31 sheets that were subjected to the accumulative roll bonding was investigated. Substantially refined microstructure of samples was achieved after the first and second pass through the rolling mill. Sheets texture was investigated using an X-ray diffractometer. Samples for tensile tests were cut either parallel or perpendicular to the rolling direction. Tensile tests were performed at temperatures ranging from room temperature up to 300 °C. Tensile plastic anisotropy, different from the anisotropy observed in AZ31 sheets by other authors, was observed. This anisotropy decreases with an increasing number of rolling passes and increasing deformation temperature. Grain refinement and texture are the crucial factors influencing the deformation behaviour.

Effect of Accumulative Roll Bonding of an AZ31 Alloy on the Microstructure and Tensile Stress

Microstructure and texture of magnesium alloy AZ31 sheets subjected to accumulative roll bonding (ARB) were studied after 1 and 2 passes through the rolling mill. Sheets after the ARB process exhibited a very fine grain structure and significant basal texture. Tensile experiments were performed at room temperature. Distinctive planar anisotropy of mechanical properties was estimated. This anisotropy is explained by the slip crystallography and twinning.
