Microstructure of AZ31 magnesium alloy sheets processed by differential speed rolling;

The objective of this study on microstructure and grain orientation of AZ31 magnesium alloy sheets produced by differential speed rolling was to investigate the possibility of improving deformability of AZ31 magnesium alloy sheets.

It is revealed that the cold rolling texture is composed of strong incomplete α(〈110〉∥RD) fiber and relatively weak complete γ fiber(〈111〉∥ND) no matter what rolling schedule is taken on,but asymmetric rolling affects greatly the textural strength and its distribution along thickness.

By means of analyzing four high mill for its rolling torque,this paper has established a structrural modle that suit to calculate the rolling torque of cold strip mill drived through back-up rolls in asymmetric rolling.

This paper is to research the thickness distribution across the strip and it's re-lationship with roll's thermal crown in asymmetric rolling.

Microstructure and Properties Evolution of Asynchronous Rolling AZ31 Magnesium Alloy Sheets during Annealing

The magnetic rariance is studied of different thiclcness two crystallization grain-oriented silicon steel finished product, underasynchronous rolling condition, the relationship is found between the tnagnetic and finished products thickness and asynchronous speed ratio of the grain oriented silicon steels.

The results indicated that the asynchronous rolling is effective to decrease rolling passes and improve the rolled texture and magnetic properties of thin silicon steel sheets.
