چکیده
To evaluate the feasibility of nickel–aluminum (the Ni2+:Al3+ molar ratios 1.0:1.0 and 1.0:2.0 are denoted as NA11 NA12, respectively) nickel–aluminum–zirconium type Ni2+:Al3+:Zr4+ 0.9:1.0:0.09 0.9:2.0:0.09 NAZ1 NAZ2, hydroxides for Cr(VI) removal from aqueous media, adsorption capability mechanism using above-mentioned adsorbents were investigated in this study. The quantity adsorbed onto NA11, NAZ1, NAZ2 was 25.5, 25.6, 24.1, 24.6 mg g−1, respectively. However, aluminum (base metal) released (approximately 0.14 g−1) higher than that 1.0 µg g−1), indicating more suitable NA11. In addition, effects pH, contact time, temperature on evaluated. Moreover, to elucidate elemental distribution, X-ray photoelectron spectrometry spectra, ion exchange also determined. surface easily desorbed a sodium hydroxide solution under our experimental conditions. information regarding study can be useful removing media.

Creep of Ni-Al and Ni-Cr-Al Superalloy Foams
The steady-state creep rate of Ni-base metallic foams, with superalloy composition (in wt. pct) Ni7.8∼9.1Al (relative density, ρ = 2.5-2.6) and Ni-13.5∼16.6Cr-5.1∼8.9Al (ρ = 2.8∼3.0), was measured under a range of temperatures (680∼825°C) and applied stresses (0.1∼0.3 MPa), and compared with that of NiAl intermetallic foams (ρ = 5.3). The stress exponent and activation energy are within the exp...

Diffusion couples combining a hcp Zr90Al10 supersaturated solid solution with a fcc Cu64Ni36 solid solution were annealed at 410 °C for different times. The reaction at the interface was investigated by transmission electron microscopy and energy dispersive x-ray spectroscopy. The investigations show the formation of a noncrystalline layer at the interface between the two solid solutions that g...
