Texture development in a warm rolled AZ31 magnesium alloy

Effect of plane strain on microstructures and texture, through the reduction ratio of AZ31 Mg alloy

“…The other figures show a typical texture of 0 0 0 1 //ND with plane strain. It is noted that the intensity of 0 0 0 1 //ND was reduced with an increased reduction ratio of plane strain, corresponding to the recent results reported by Jeong and Ha [29]. While our current observations agree with Mg alloys from shear strain due to the friction between the roll and the sample (i.e., conventional rolling), it should be specially noted that the DRX grains with high reduction ratio was achieved by one single pass and the AZ31 sheet was maintained plane strain condition.…”

Effect of Ca addition on microstructure of twin-roll cast AZ31 Mg alloy

“…It has been shown in the present study that TRC AZ31 and AZ31-0.7Ca alloys have weaker basal textures than ingot cast AZ31 alloy. It is known that predominant basal texture forms as a result of rolling at high temperature [17]. Considering that TRC alloys have been subjected to a smaller amount of rolling reduction than ingot cast alloy (50 % vs. more than 90 %), it can be thought that such difference in the intensity of basal texture between TRC alloys and ingot cast alloy is due to the difference in the amount of rolling reduction they have received.…”

Rolling Texture Evolution of AZ31 Magnesium Alloy Sheets by Isothermal Eccentric-Rolls Drawing

“…1) But, unfortunately, such a sheet was confined to a subset of narrow coiled strips. Although a relationship between rolling conditions and textures was discussed in some reports, [2][3][4][5] the rolling reduction by one-pass was limited not to crack with drop in temperature. In the highspeed rolling, in which the generated heat by deformation exceeds the lost heat to rolls, the double peak texture was obtained in reduction above 40%.…”
