of the white net is roughly estimated to be about 4%, and the thickness of the white imaging layers is less than 1 μm. Quantitative EDS analysis suggests that the bright phases in Fig.3(a) are enriched... phase in the as-cast Ti-43Al-4Nb alloy can be removed by the heat treatment process. 4 Discussion 4.1 Solidification process The ingot has uniform fine-grained microstructure composed of lamellar......
in a mass ratio of 1:4. The mixture was cold pressed under a pressure of 35 MPa into round electrode pellets of 10 mm in diameter and total mass of about 1 g. The electrochemical hydrogen storage kinetics... discharge, the test electrodes in the fully charged state were discharged at 500 mV potential steps for 4 500 s on electrochemical workstation (PARSTAT 2273), using the CorrWare electrochemistry corrosion......
to interface (b) Detailed microstructural characterization of the Fe-based coating was analyzed by TEM, which is shown in Fig. 4. The bright field TEM image indicates that Fe-based coating consists of block-like grains, and the corresponding SAED pattern clearly reveals that it contains heteromorphy Fe2Ti phase. Fig. 4 TEM image (a) and corresponding SAED pattern (b) of Fe-based coating 3.2 Microhardness......
with respect to sintering method and conditions are outlined in Fig. 4. Fig. 3 Photo (a) and dimensions (b) of specimen for tensile test Fig. 4 Changes of relative density from <147 μm CP-Ti powders..., via SPS and HP, densification is achieved while suppressing the grain growth, resulting in titanium consolidation with superior mechanical properties, such as hardness and strength. 4 Conclusions 1......
micrographs shown in Fig. 4 demonstrate that the Ca-P layer formed from SBF solution consists of white particles with loose structure. At high magnification (×20000), the Ca-P film is composed of globules... the range of dozens of microns. Fig. 4 Surface morphology of TiNi alloys sintered at different temperatures: Two kinds of TiNi samples after grinding, acid etching, alkali treatment are assessed by XRD......
generated forging effects in the force profiles, the force escalation is easily predictable. Let’s look at Figs. 4(a) and (c) for force profiles which are also escalated by the electrically generated forging forces. The force escalation is simply marked with circled capital letters such as A, B and C. The corresponding dynamic resistive patterns are shown in Figs. 4(b) and (d) for the pneumatic......
) Carbon atoms move towards Al3Ti particles due to their high affinity towards Ti. 4) Reaction occurs between Ti and C atoms in a gap from Al3Ti surface to form TiC. 5) Due to smaller size, carbon... AMCs having various contents of TiC particles are depicted in Figs. 4(a)-(c). The effect of TiC content on the average grain size of AA6061/TiC AMCs is furnished in Fig. 4(d). The EBSD maps exhibit......
can be calculated at eight different operating temperatures, and the curves of response vs temperature (T) are shown in Fig. 4. With increasing operating temperature, the response of BNdT films.... The optimum working temperature of 100 °C for all BNdT films is applied in all investigations hereinafter. Fig. 3 FE-SEM images of BNdT-1 (a) and BNdT-2 (b) Fig. 4 Responses of BNdT-1 and BNdT-2 to 1......
strength, σb, decrease (Figs. 4(a, b)) with increasing temperature. The temperature dependence of yield strength might be attributed to the thermally induced change in dislocation width which makes... are shown in Fig. 4(d). It can be found that the n value decreases with increasing content of bcc phase. Fig. 3 Engineering stress-strain curves of specimens for Alx alloys at room temperature......
voltages Fig. 4 Pore size distribution of surface topography on SEBM-TC4 samples after MAO at different voltages Figure 3 presents the typical surface morphologies of MAO coating at different voltages on SEBM-TC4 substrate. It is seen that the surface is covered with different-size pores, and the sizes and shapes of pores change greatly with the applied voltage increasing. As shown in Fig. 4......
