Mechanical Behaviour of Pure Aluminum Processed by Constrained Groove Pressing
In recent years, the fabrication of bulk materials with ultra fine grain sized materials processed by SPD methods. Different techniques have been used to introduce large plastic strains in to bulk metals such as Equal Channel Angular Pressing (ECAP) [1-3], Accumulative Roll Bonding (ARB) [4-7], Repetitive Corrugation and Straitening (RCS) [8,9], Constrained Groove Pressing (CGP) [5] and Constra...
متن کاملTailoring microstructure of Mg–Zn–Y alloys with quasicrystal and related phases for high mechanical strength
The occurrence of a stable icosahedral (i-) phase, which is quasicrystalline with an icosahedral (fivefold) symmetry, on the equilibrium phase diagram of Mg-Zn-RE (RE = Y, Gd, Tb, Dy, Ho or Er) alloys opened up an interesting possibility of developing a new series of magnesium alloys for structural applications. Alloys based on the i-phase have been studied for the past 14 years. Ultra-high str...
متن کاملMulti-objective optimization of geometrical parameters for constrained groove pressing of aluminium sheet using a neural network and the genetic algorithm
One of sheet severe plastic deformation (SPD) operation, namely constrained groove pressing (CGP), is investigated here in order to specify the optimum values for geometrical variables of this process on pure aluminium sheets. With this regard, two different objective functions, i.e. the uniformity in the effective strain distribution and the necessary force per unit weight of the specimen, are...
متن کاملAchieving High Strength and Good Ductility in As-Extruded Mg–Gd–Y–Zn Alloys by Ce Micro-Alloying
In this study, the effect of Ce additions on microstructure evolution of Mg-7Gd-3.5Y-0.3Zn (wt %) alloys during the casting, homogenization, aging and extrusion processing are investigated, and novel mechanical properties are also obtained. The results show that Ce addition promotes the formation of long period stacking ordered (LPSO) phases in the as-cast Mg-Gd-Y-Zn-Ce alloys. A high content o...
