The present work deals with studies on the dynamic behavior of ultrafine grained AA2519 alloy synthesized via cryogenic forging (CF) and room temperature forging (RTF) techniques.
50 mV s-1, then inlet CO untill saturation and recorded the CVs.The ECSA was calculated by the following equation: ECSA = Q/(0.42 ×M), where Q (mC) is the charge for the CO adsorption. 0.42 (mC/cm2) is the electrical charge associated with full monolayer adsorption of CO on Pt.
12%The potential of producing nanocrystalline and ultrafine-grained materials by inducing a large amount of plastic strain accompanied by a large enhancement in the mechanical properties has attracted attentions on the equal-channel angular pressing (ECAP) process [].The basis of ECAP is pressing a work-piece using a punch through a die containing …
Transition metal oxides are promising anode materials for lithium-ion batteries thanks to their good electrochemical reversibility, high theoretical capacities, high abundance, and low cost. The mechanism of lithium insertion or deintercalation into or from these metal oxides can be different depending upon their lattice structure or chemical nature. Synergistic effects obtained from …

The fine scans for the (110) peak of BCC phase and (111) peak of FCC phase of AlCoCrFeTi 0.5 Ni x alloys are illustrated in Fig. 1b. With the increase in x from 0 to 1.5, the (110) peak for B2 phase splits into two peaks, which are corresponding to A2 and B2 phases. The (110) peak of B2 phase shifts towards a lower 2θ angle while the (110) peak of A2 phase shifts towards a …
FT-IR, NMR, XPS, and XRD were conducted to verify the changes of the chemical structure at each of the steps. In the first step, the characteristic band of the carbonyl group at 1745 cm −1 appeared for all three materials, and the peak strength of the hydroxyl group at 3335 cm −1 significantly decreased, indicating that some of the hydroxyl groups were substituted by …

The erosion characteristics of gunmetal have been evaluated practically at different operating conditions. Asymmetrical silica sand (SiO 2 ) is taken into account as erodent within range of 300–600 μ m. The impact velocity within 30–50 m/sec, impact angle 15–900, and stand off distance 15–25 mm are inspected as other relevant operating test conditions.

The traditional alloy design concept combines one or two principal elements with additional minor elements, an approach that restricts the development and application of alloys due to the limited compositional space explored ().Thus, to enable the pursuit of alloys with special microstructures and properties, such as high strength, new design concepts are needed.
