Bendability of the wrought magnesium alloy AM30 tubes using a rotary draw bender
چکیده انگلیسی

The influences of temperature, bending velocity and original grain size on the bendability of tubes have been investigated. The cross-section ovality and released spring back rate decrease with increasing temperature, while the maximum wall-thinning rate reaches the minimum at the moderate temperature. With increasing bending velocity, the wall-thinning rate and ovality increase, while the change of spring back rate exhibits an opposite trend. In addition, the wall-thinning rate, ovality and spring back rate increase with the accretion of original grain size. The results suggest moderate temperature, lower bending velocity and small original grain size are beneficial to the reduction of maximum wall-thinning rate, cross-section ovality and released spring back rate.
