the full annealing aa6061 aluminum alloy was subjected to severe plastic deformationvia the combination of equal channel angular pressing (ecap) and cold rolling (cr) in order torefine its microstructure and to improve its mechanical properties. according to the results of hotand cold tensile tests, the combination of ecap and cr significantly affected the final strengthand ductility of studied...

-In this paper a Lagrangean decomposition technique for solving the scheduling problem for Hot Charged Rolling (HCR) in the continuous casting process which involves sequencing and grouping. This Lagrangian relaxation algorithm is proposed that incorporate two sets of constraints into the objective function after applying the variable splitting technique. The relaxed problem has a special struc...

specific strength, high specific stiffness, and many other advantages (Mordike et al., 2001). With the increased consciousness of energy saving and environmental protection, Mg alloys are becoming widely recognized as the candidates to replace steel and aluminium alloys in many fields, such as in vehicles and the electronics industry. Mg alloys are thus becoming known as new ‘green’ engineering...
