, LANGDON T G. Using ECAP to achieve grain refinement, precipitate fragmentation and high strain rate superplasticity in a spray-cast aluminum alloy[J]. Acta Materialia, 2003, 51(20): 6139-6149. [53......
plays an important role in the increase of the liquid metal embrittlement. Some secondary phases will precipitate when materials are exposed to high temperature for a sufficient time, which have......
, the content of silica was low, and the siliceous materials dissolved in fluids did not precipitate until supersaturation. Figure 6 Tectonic-diagenetic-pore evolution sequence of Bashijiqike formation......
by a simple co-precipitation method, in which an aqueous mixture of ammonium carbonate and ammonium hydroxide was used to precipitate Li+ and Nb5+ cations as carbonate and hydroxide that were calcined at 700......
between the bulk of the grain and the grain boundaries, where intermetallic phases precipitate [69]. Fig. 19 Schematic of path and onset of corrosion In summary, the addition of Ni to the Al-5wt.%Cu......
medium, metal ions adsorb on sphalerite surfaces in the form of sulfide precipitate, which is easily redissolved into the solution. Therefore, the optimum pH for metal ion activation of sphalerite......
