Dynamic strain aging of a commercial Al–Mg–Si–Cu alloy during equal channel angular extrusion process

Electron microscopy studies of the age-hardening behaviors in 6005A alloy and microstructural characterizations of precipitates

“…In recent years, a number of fabrication techniques and alloying methods have been developed to research the effects on the precipitation hardening behavior and the microstructural development during artificial aging in Al-Mg-Si-Cu alloys, and further to increase the mechanical strength of alloys [2][3][4][5]. In particular, the precipitation strengthening through some metastable nano-particles precipitated from the matrix, as one of the most essential techniques, is still widely researched [6][7][8].…”

Microstructures evolution and phase transformation behaviors of Ni-rich TiNi shape memory alloys after equal channel angular extrusion

“…As one of the SPD methods, the equal channel angular extrusion (ECAE) technique was first introduced by Segal and his colleagues in 1970s and 1980s [2,3]. The method had been applied in the production of various ultrafine grain materials successfully, such as TiNi alloys [4][5][6][7][8][9][10][11][12], TiAl alloys [13], Ti [14][15][16], Mg, Al and Cu alloys [17][18][19][20][21][22][23][24][25] and some interesting results were obtained [26][27][28][29].…”

Friction Stir Welding Parameters: Impact of Abnormal Grain Growth during Post-Weld Heat Treatment on Mechanical Properties of Al–Mg–Si Welded Joints

“…The serration behavior caused by the Portevin-Le Chatelier effect [44] was observed before σ UTS points in the as-welded samples. This serrated yielding represents the plastic instability during the tensile test [44,45].…”
