, physical/ chemical methods. Method 1312, synthetic precipitate leaching procedure [S]. Washington DC, 1994. [37] HJ/T299-2007. Chinese EPA. Solid waste-extraction procedure for leaching toxicity......
reductions was close to the set value. All the specimens were air cooled after hot working. Secondary α would precipitate from β matrix during cooling. The transformed β matrix was easily distinguished from......
of a material is determined by its microstructure, i.e., by the microstructural constituents that precipitate during solidification, which are strongly related to the choice of process technology..., PEKGULERYUZ M. Enhanced mechanical properties of an Al-Si-Cu-Mg alloy at 300 °C: Effects of Mg and the Q-precipitate phase [J]. Materials Science and Engineering A, 2015, 621: 277-286. [33] HASSAS-IRANI S......
, with SO42- added, the precipitate was formed due to the combination of Pb(II) and Cd(II) with SO42-, which resulted in the decrease of desorption of Pb(II) and Cd(II). That was expressed......
as the increase in inoculation percent raises the cell concentration in the medium and leads to better extraction of metals. But increasing inoculation percent causes some ions to precipitate on the ore......
, the supersaturated Cr atoms dissolved in the Cu matrix continue to precipitate and the solute scattering resistance gradually decreases. With the decreasing of the dislocation density and the continuous......
is 1%-2%, which can improve strength by solid-solution strengthening. When Zn content is 4% or 6%, MgZn phases precipitate from the matrix. This effect enhances the strength by dispersion......
precipitate corresponding to γ-MgZn phase was observed in the α-Mg matrix of Mg-10%Zn alloy. Figure 2 shows that most of the peaks of the sintered alloys shifted to the left (lower Bragg’s angle......
