Mechanical properties of ultra-fine grained AZ91 magnesium alloy processed by friction stir processing

Influence of fibre distribution and grain size on the mechanical behaviour of friction stir processed Mg–C composites

“…This is consistent with numerous previous reports according to which FSP induces a strong texturing of Mg alloys [see e.g. 18,[34][35][36][37]. It has been shown that the basal plane generally tends to orient along the material flow.…”

Microstructural evolution of AZ61-10at.%Ti composite powders during mechanical milling

“…With grain refinement, the ductility is also available to increase due to activation of non-basal slip based on the compatibility stresses near the grain boundaries. Basically, preparation of UFG magnesium alloys can be achieved by equal channel angular extrusion pressing (ECAE/ECAP) [10], friction stir processing (FSP) [11], high pressure torsion (HPT) [12], powder metallurgy (PM), and so forth. However, due to the rapid growth kinetics of the single-phase crystals, most grain refining processes except for partial plastic deformation and tiny component forming are limited to micron crystalline.…”

A Review on Superplastic Formation Behavior of Al Alloys

“…To enhance the superplastic formability of Al alloys, it is necessary to make the alloys to go through several advanced forming technologies, such as flake powder metallurgy [16] and cryo-deformation [17][18][19][20] as well as severe plastic deformation (SPD) [21], including friction stir processing (FSP) [22][23][24][25][26][27][28], equal-channel angular pressing (ECAP) [29][30][31][32][33][34][35], high-pressure torsion (HTP) [36], accumulative roll bonding (ARB) [37], multiaxial alternative forging (MAF) [38], and repetitive corrugation and straightening (RCS) [39,40]. After SPD process, ultrafine grain, high superplasticity, and low flow stress are available for Al alloys.…”
