Using LBR-370 numerical control lathe, high speed cutting was applied to AZ31 magnesium alloy. The influence of cutting parameters on microstructure, surface roughness and machining hardening were investigated by using the methods of single factor and orthogonal experiment. The results show that the cutting parameters have an important effect on microstructure, surface roughness and machine hardening. The depth of stress layer, roughness and hardening present a declining tendency with the increase of the cutting speed and also increase with the augment of the cutting depth and feed rate. Moreover, we established a prediction model of the roughness, which has an important guidance on actual machining process of magnesium alloy.

The work reports an experimental observation on crystal rotation in a duplex (austenite + ferrite) steel induced by the electropulsing treatment at ambient temperature, while the temperature rising due to ohmic heating in the treatment was negligible. The results demonstrate that electric current pulses are able to dissolve the initial material’s texture that has been formed in prior thermomechanical processing and to produce an alternative texture. The results were explained in terms of the instability of an interface under perturbation during pulsed electromigation.

“…Moreover, this double-peak distribution phenomenon cannot be observed in the global texture analysis, because of the low volume fraction of tension twins. In contrast, a reversed phenomenon can be observed with further deformation (3-6 passes), the texture intensity is gradually decreased, which may be related to the recrystallization process [36,37]. More importantly, a non-basal texture component has been gradually formed, because the grain refinement is beneficial to the activation of prismatic or pyramidal slip systems.…”

In this study, the mechanical properties and damping capacities of cast Mg-5.5Zn-0.6Zr (weight percent, ZK60) alloys have been simultaneously improved by a facile multi-directional forging (MDF) processing, and the mechanisms of microstructure evolution and texture modification are systematically investigated. The activation of tension twinning occurs during the initial MDF stage, due to the coarse-grained structure of the as-cast alloy. With increasing MDF passes, the continuous dynamic recrystallization (CDRX) results in a fine equiaxed-grain structure. The typical non-basal texture is formed in the as-MDFed alloy for 6 passes, with the (0001) planes inclined 60°-70° to forged direction and 10°-20° to transverse direction, respectively. A good balance between the strength (~ 194.9 MPa) and ductility (~ 24.9%) has been achieved, which can be ascribed to the grain refinement, non-basal texture and fine precipitate particles. The damping capacity is remarkably improved after MDF processing, because the severe deformation increases the dislocation density, which effectively enlarges the sweep areas of mobile dislocations.
