“…This would be especially useful whens tudying the effects of alloying additions on the stability of intermetallic phases in wrought aluminum alloys, for example. [34,52,53,54] IV.C ONCLUSIONS Al-Fe-Si intermetallic particles in cast eutectic Al-Si alloys are usually categorized by morphology and/or EDS, and relatively little work has been done previously to identify these particles by crystallographic analysis. The results of an earlier EBSD surveyo fal arge number of Al-Fe-Si particles in an Al-11 pct Si alloy [42] were supported by the present electron diffraction study of thin foil specimens of the same alloys.…”

Al-Fe-Si intermetallic particlesinboth unmodified and highly modified sand-cast eutectic Al-11.7pct Si alloys were characterizedusing scanning and transmission electron microscopy,energy-dispersive X-ray spectroscopy,and convergent beam and selected area electron diffraction. The only twoAl-FeSi intermetallics observed in this particulara lloy are (1) ''Chinese-script''m orphology,c onsistent with ad escription of body-centered cubic a -Al 19 Fe 4 MnSi 2 and (2) plate-shaped, consistent with tetragonal d -Al 3 FeSi 2 .T he authors are unaware of any otherc haracterization of d -Al 3 FeSi 2 using convergent beam electron diffraction (CBED) and selected area diffraction (SAD) techniques.

“…This is attributed to the increased heat input used during the welding of the thicker materials. Presented and discussed in detail elsewhere [18], an examination of the microstructure of the area immediately around the fillet revealed a few instances of visible secondary melting ( Figure 12). For the remaining alloys and thicknesses chosen, the provisions within the 2010 Aluminum Design Manual allowing the use of 85%.…”

“…These intermetallic particles result from the presence and availability of residual elements, such as iron and silicon [18,19]. As documented elsewhere, these particles were identified to be Al 12 Fe 3 Si, Al 15 (FeMn) 3 Si and Al 5 FeSi [18][19][20]. The iron-rich intermetallic particles range in size from 1 to 10 microns and are potential sites for the early initiation of microscopic damage during plastic deformation.…”

“…The as-received alloy revealed a random distribution of both coarse and intermediate size intermetallic particles (Figure 3a,b). These intermetallic particles result from the presence and availability of residual elements, such as iron and silicon [18,19].

Abstract:The conjoint influence of welding and artificial aging on mechanical properties were investigated for extrusions of aluminum alloy 6063, 6061, and 6005A. Uniaxial tensile tests were conducted on the aluminum alloys 6063-T4, 6061-T4, and 6005A-T1 in both the as-received (AR) and as-welded (AW) conditions. Tensile tests were also conducted on the AR and AW alloys, subsequent to artificial aging. The welding process used was gas metal arc (GMAW) with spray transfer using 120-220 A of current at 22 V. The artificial aging used was a precipitation heat treatment for 6 h at 182˝C (360˝F). Tensile tests revealed the welded aluminum alloys to have lower strength, both for yield and ultimate tensile strength, when compared to the as-received un-welded counterpart. The beneficial influence of post weld heat treatment (PWHT) on strength and ductility is presented and discussed in terms of current design provisions for welded aluminum light pole structures.

“…The 6xxx-series aluminium alloys contains magnesium and silicon as major alloying elements [6][7][8][9][10][11][12]. These multiphase alloys belong to the group of commercial aluminum alloys, in which relative volume; chemical composition and morphology of structural constituents exert significant influence on their useful properties [1,[6][7][8][9][10][11]. Al-Mg-Si alloys that combine good strength, extrudability, favorable corrosion resistance with low cost have recently been used for automotive body sheet panel for weight saving, furniture, architectural facing and structures and transport vehicle frames.…”

The hot deformation behavior of the 6xxx aluminum alloys was investigated by compression tests in the temperature range 100• C-375• C and strain rate range 10 −4 s −1 and 4x10 −4 s −1 using dilatometer DIL 805 BÄHR Thermoanalyse equipped with accessory attachment deformation allows the process to execute thermo-plastic in vacuum and inert gas atmosphere. Associated microstructural changes of characteristic states of examined alloys were studied by using the transmission electron microscope (TEM). The results show that the stress level decreases with increasing deformation temperature and deformation rate. And was also found that the activation energy Q strongly depends on both, the temperature and rate of deformation. The results of TEM observation showing that the dynamic flow softening is mainly as the result of dynamic recovery and recrystallization of 6xxx aluminium alloys.Keywords: Aluminum alloy, Hot deformation, Microstructural evolution, Activation energy Obróbkę cieplno-plastyczną stopów aluminium grupy 6xxx prowadzono w zakresie temperatury 100• C-375• C i prędkości odkształcania 10 −4 s −1 i 4x10 −4 s −1 na dylatometrze DIL 805 BÄHR Thermoanalyse wyposażonym w przystawkę odkształ-ceniową umożliwiającą wykonanie procesu odkształcania w próżni i w atmosferze gazu obojętnego. Zmiany mikrostruktury badanych stopów, zachodzące w charakterystycznych stadiach obróbki cieplno-plastycznej, badano za pomocą transmisyjnego mikroskopu elektronowego (TEM). Ustalono, że wielkość naprężenia zmniejsza się wraz ze wzrostem temperatury i wielkości odkształcenia. Również energia aktywacji Q w dużym stopniu zależy zarówno od temperatury jak i prędkości odkształcania. Wyniki obserwacji mikrostruktury TEM wykazały, że dynamiczne mięknięcie materiałów jest głównie wynikiem zachodzących procesów zdrowienia dynamicznego i rekrystalizacji stopu aluminium 6xxx.
