The binary diagram of Zn-Al [1-4] is quite complex, but the alloy under the eutectoid temperature contains basically two phases; phase α rich in Al with K12 lattice and phase η Zn-rich with lattice H12.
Light lamellae represent phase α, which was Al-rich.
Their semi-quantitative analysis showed 95.2 % Zn, 4.8 % Al.
Semi-quantitative EDX analysis of phase ε showed 82.8 % Zn, 3.1 % Al, 14.1 % Cu.

Impact of high speed incremental forming on material properties of AA6082 sheets Giuseppina Ambrogio 1, a *, Stefania Bruschi2,b , Francesco Gagliardi1,c , Andrea Ghiotti2,d, Luigino Filice1,e 1Dept. of Mechanical, Energy and Management Engineering, University of Calabria - Italy 2Department of Industrial Engineering, University of Padova - Italy ag.ambrogio@unical.it, bstefania.bruschi@unipd.it, cf.gagliardi@unical.it, dandrea.ghiotti@unipd.it, el.filice@unical.it Keywords: Incremental Sheet Forming, High Speed, Aluminum.
Among them, the use of modified tool path strategies proposed by Ambrogio et al. in 2005 [2], the uses of multiple tools proposed by Cheng et al. in 2005 [3], the application of heating sources to reduce material strength proposed by Duflou et al. in 2007 [4] and, finally, the use of multistep sequences proposed by Ambrogio et al. in 2011 [5] are probably the most suitable to overcome process inaccuracy.
Finally, with respect to the AA6082-T6 maximum wall inclination angle allowed by ISF [1], a slope of 45° was applied for all the tests. 20 mm Chemical Composition %Al %Cr %Cu %Fe %Mg %Mn Other 92.5 – 98.3 <0.25 <0.1 <0.5 0.6-1.2 0.4-1.0 <0.15 Ultimate Tensile Strength Hardness Roughness 300 MPa 105±2 HV 1.8±0.05 mm Figure 3: Material characteristics in the as-received condition.

MPTMS modified ITO glass has been employed by Cheng et al. for the synthesis of gold nanoparticles [14].
Wang et al. synthesized 15nm colloidal gold particles on the surface of ITO substrate, which was modified with APTMS to yield an interface for the assembly of colloidal gold [15].
To overcome the disadvantage of assembling with polymer, Oyama et al. developed seed-mediated growth method to attach gold nanoparticles onto ITO substrate without using organic linker [16-18].
Dai et al. employed GNPs modified ITO electrode prepared by direct electrochemical deposition to detect arsenic (Ⅲ) through linear sweep voltammetry for the first time [19].
