Hidalgo Alcalde, Pedro ; Cepeda Jiménez, C. M. ; Ruano, O. A. ; Carreño, F. | Trans Tech Publications Ltd | 2010The 7075 Al alloy was processed by accumulative roll bonding (ARB) at 300, 350 and 400 ºC. The microstructure and texture were characterized and the hardness was measured. Cell/(sub)grain sizes less than 500 nm and typical beta-fibre rolling tex[...]texto impreso
Hidalgo Alcalde, Pedro ; Cepeda Jiménez, C. M. ; Ruano, O. A. ; Carreño, F. | Royal Soc Chemistry | 2010Bulk CZT crystals doped with Bi (1 x 10(19) at/cm(3)) have been grown by the Oscillatory Bridgman method, the growth velocity and the zinc concentration profile being improved by the insertion of a Pt tube acting as a cold finger. The stoichiome[...]texto impreso
Cepeda Jiménez, C. M. ; Hidalgo Alcalde, Pedro ; Pozuelo, M. ; Ruano, O. A ; Carreño, F. | Elsevier Science SA | 2010-04-25The microstructure and mechanical properties in the interface region of a multilayer composite laminate based on Al-Zn (Al 7075) and Al-Cu (Al 2024) alloys have been mainly characterized by EBSD and shear tests. It is shown that varying solution[...]texto impreso
Cepeda Jiménez, C. M. ; Hidalgo Alcalde, Pedro ; Pozuelo, M. ; Ruano, O. A. ; Carreño, F. | Springer | 2010-01Two aluminum multilayer laminates have been processed by hot roll bonding following similar processing paths. The first one is constituted by alternated Al 2024 and Al 1050 layers (ALH19) and the second one by alternated Al 7075 and Al 1050 laye[...]texto impreso
The 7075 alloy is an Al-Zn-Mg-Cu wrought age-hardenable aluminum alloy widely used in the aeronautical industry. The alloy was accumulative roll bonded at 300 A degrees C (573 K), 350 A degrees C (623 K), and 400 A degrees C (673 K), and the mic[...]texto impreso
Cepeda Jiménez, C. M. ; Hidalgo Alcalde, Pedro ; Pozuelo, M. ; Ruano, O. A. ; Carreño, F. | CENIM | 2010The microstructure and mechanical properties in the interface region of a multilayer laminate based on high strength aluminium alloys, Al 7075 and Al 2024, have been characterized mainly by EBSD and shear tests. It is shown that the time of solu[...]texto impreso
Cepeda Jiménez, C. M. ; Hidalgo Alcalde, Pedro ; Carsi, M. ; Ruano, O. A. ; Carreño, F. | Elsevier Science SA | 2011-03-25Hot torsion tests to fracture to simulate thermomechanical processing were carried out on a solution-treated Al-Cu-Mg alloy (Al 2024-T351) at constant temperature. Torsion tests were conducted in the range 278-467 degrees C, and at two strain ra[...]
