trace amount of heavy metals are harmful to the human body, especially cadmium (Cd) is well-known as one of the most toxic metals even at low concentrations due to the low excretion rate of body. However... are used for removal of heavy metal ions from aqueous solutions. Among these methods, adsorption is considered to be the most promising technique because it is relatively low-cost, highly efficient......
of crude lead has many disadvantages in fire refining process and electrolytic process [28], for example, high metal content in tailing, low direct rate of crude lead and environmental pollution in fire refining process, high energy consumption and long production duration in electrolytic process. But vacuum metallurgy has many advantages [28], such as short flow, environmental protection and low......
was defined with a 10 mm×10 mm working surface with epoxy resin. One end of the electrochemical test sample was connected with copper wire, and the rest other than the working surface (l.00 cm2... to 230 °C and 250 °C, the hardness of Mg–0.25Y alloy fluctuates within a small range due to low content of Y, but the hardness basically keeps unchanged, which also shows the good thermal stability......
, 25(6): 1340–1349. DOI: https://doi.org/10.1007/s11771-018-3830-8. 1 Introduction Al–Cu–Li alloys are extensively used for aerospace applications due to their low density, high elastic modulus and high.... As reported in Refs. [6–8], a high level of Li usually facilitates the formation of the metastable δ' phase. When the Li concentration is low [9–11], the alloys prefer to form T1 or θ', and which one......
, Fe2Al5 and FeAl were successfully fabricated on low carbon steel [10]. Moreover, occurrence of a mixture of phases including Al-rich Fe2Al5, FeAl, Fe3Al, and a Fe(Al) solid solution, varied significantly... the corrosion resistance in a low chlorinated medium [21]. However, aluminum-rich aluminides (Fe4Al13 and Fe2Al5) as the thermodynamic favored intermetallic phases in Fe-Al reaction system have......
recrystallization (DDRX) during hot working for metals with low to medium stacking fault energies quantitatively, a new physically-based model was proposed by considering the characteristics of grain size..., discontinuous dynamic recrystallization (DDRX) taking place by nucleation and growth in materials with low to medium stacking fault energies (SFEs), plays a crucial role in grain refinement and hence has been......
Bayer red mud accounts for a large amount because of the relative simple process, low lost and high-quality product [5–8]. However, the Bayer red mud contains high alkali and low activity, thus...] and catalyst for enhanced nitrate reduction [18] owing to its alkalinity, composition and low costs. Some researches such as the flue gas desulfurization have been conducted [19, 20]. ELISABETTA et al......
profiles exhibited by low angle reflection is governed by small grain size while the higher angle reflection corresponds to the internal strain [42]. Since the MA process involves the imposition... of SSSS of low diffusivity elements, Fe and Cr, in Al matrix is another contributing mechanism in improving the thermal stability of the developed alloy. 4 Discussion The transition metals (TMs), Fe......
