625 [21] and Inconel 600 [19]. As mentioned above, the austenite phase has a relatively low SFE; thus, it could undergo the DDRX mechanism during the FSW process. Similar to the SZ of SAF 2507......
]. The extraction methods have been widely investigated in the past decades, including ion exchange, coagulation or coprecipitation, and adsorption process [6-8]. Typical coprecipitation method is limited..., although this is important for the practical extraction of selenium from copper anode slime leachate. Herein, the effort to apply Ca-Al-Cl-LDHs on the adsorption of Se(VI) in the alkaline condition was made......
be described by Z parameter () [29]. DRX is generally more pronounced at lower Z values. With the decrease of Z value, the main softening mechanism of the alloy transformed from DRV to DRX. According......
time and reduces fine precipitates by grain coarsening mechanism. As a result of higher TA (3°), the weld region subjected to severe friction causes high heat input by excess forging of tool. Hence......
to the mechanism and implementation effect of ICR treatment. Obvious plastic deformation zones are generated in ICR-treated surfaces and cracks become closed [7, 13]. However, related tests have been conducted using......
. Ablation behavior and mechanism of C/C-ZrC-SiC composites under an oxyacetylene torch at 3000 ℃[J]. Ceramics International, 2013, 39: 4171-4178. [49] LU J H, HAN K, LIU L, LI H J, LI K Z, QU J L, YAN X......
on sizing and extraction processes thereafter 2.3 Analytical instrument procedures Atomic force microscope (Model XE-70) from Park Instruments was used to characterize the surface of the sized... while the oxygen concentration decreased. Virgin fibers exhibited a small change in the concentration of the elements investigated (<1% difference). As the fibers were subjected to the extraction......

by nanomechanical restraint (Orowan mechanism) [36]. The higher dispersion of Co3O4 particles in the presence of SLS increases the adsorption on cathode surface which enhances the nucleation rate... in the bath up to 4.2 wt.% at 2 g/L of Co3O4 particles (NSC2) and thereafter it decreases [16]. During deposition, the adsorption of particles on cathode surface from plating bath increases......
, N2 adsorption-desorption, TG, NH3-TPD, Py-FTIR and SEM. Details of characterization methods and instruments are given in supporting information. 3 Results and discussion 3.1 Characterization The textural properties of H-ZSM-5 catalyst were determined using N2 adsorption isotherm, while the relevant results are presented in Table 1. The BET surface area and pore volume were 389 m2/g and 0.231......
