These alloys are AA2024-T3 (Al-Cu) and AA2099-T8E77 (Al-Cu-Li) and are both in the plate format.
Ma et al [6] did, however, observe that Li sat with Al-Cu-Mn dispersoids (~1 µm x 200 nm).
Ma et al [6] also showed that nanometre sized Al-Cu-Mn-Li dispersoids were also linked to the propagation of the pitting corrosion.

In late 2011, huge super-elasticity was discovered in two main polycrystalline Fe-based shape memory alloy systems; the Fe-Mn-Al-Ni and Fe-Ni-Co-Al-Ta-B [2].
The formation of this serrated interface phase at the grain boundaries could be a result of short-range diffusion of Mn and Al across the BCC/FCC boundaries, whereby due to Al being a BCC stabilizer and Mn being FCC stabilizer would result in local segregations.
Similar microstructural behavior was reported by J.M Vallejos et...al 2021 [9].

Fig. 8 shows three hysteretic curves in the same position of a damper under three analysis cases under effect of EL wave.
In the first 10 seconds of the EL wave, response of structure was small, damping force of viscous damper was obviously larger than viscoelastic damper, consuming more energy; Interlayer velocity of VDS was smaller than VEDS in 10 second to 30 second of EL wave.
Under effect of EL seismic wave, the maximum seismic response of structure appears between 17 second and 30 second, so excellent energy dissipation capacity in low velocity of viscous damper paly an indispensable role on reducing structure seismic response in early phase.

Effect of Al3(Sc,Zr) Particles on Tensile Properties of an Al-Zn-Mg-Cu-Sc-Zr Alloy This paper is dedicated to Prof.
Introduction 7000 series Al-Zn-Mg-Cu alloys are extensively used in the aerospace industry because they possess the highest strength among all commercial Al alloys [1].

The presence of the Ashby-Brown contrast for bright-field images of these particles, as well as the common locations of the (h,k,l)Al and (2h,2k,2l)L12 electron diffraction spots, confirmed that the particles were coherent with the Al matrix.

Fly ash has become increasingly wide range of applications in expressway as a new environment friendly material, its range of applications are from the CFG( Cement Fly-ash Gravel) pile of soft ground、 pavement admixture to embankment materials et al.
Store large amount of fly ash, not only occupy large areas of agricultural land、the dust generated serious pollute the atmosphere (REES and SIDRAK. 1956；Dreesden et al. 1977; Riekerk 1983; Wong and Wong 1986; El-Mogazi et al. 1988;Menon et el. 1990; Carlson and Adriano 1993; Singh and Yunus 2000)[1-8], but also pollute groundwater system in the storage areas, furthermore, if the wet slurry discharged into rivers and lakes, would be pollute the watercourses and then directly affects the growth of aquatic organisms (Rohrman 1971)[9], and finally destruct ecological balance.
Such as, the fly ash is suggested as replacements for soil as cover material in sulfidic mine tailings (Holmström, 2000) [11]; the fly ash can form durable sealing layers due to its self-hardening properties (Steenari et al.1999) [12] and can possibly prevent the formation of acidic drainage water due to its high alkalinity; the fly ash can also used as a building materials (Wesche, et al.1989) [13].
(3) Fly ash as a subgrade filling, it should be special emphasize process control in the construction, those control include good source of fly ash、water content、compacted layer thickness、pavement and rolling et al
