for 10 min for complete dissolution. Then, a degasser, hexachloroethane (0.1%, mass fraction) is added to remove the dissolved gases from the melt. Afterward, the molten alloy is immediately poured......
[13]. However, the final products need post-processes such as machining [14]. In casting, reinforcing particles are added to a molten matrix. The major drawback of this method is the sedimentation......
composition in the fusion zone is a result of vapourisation which is adjudged to have taken place during melting of the solid metals and solidification of the molten metals. Compared with the sample 4......
cast 7075 aluminum alloy. 2 Experimental 2.1 Materials and anodizing process The superheated slurry cast 7075 Al alloy was produced by squeeze casting. The alloy ingots were molten at 750 °C... particles at grain boundaries were sensitive to chloride-induced corrosion [30]. Moreover, corrosion pitting is evident in images of the anodized samples H1-2-15-15, H1-2- 25-15, H2-B2-2-25-5......
deposited tantalum from molten salt[J]. Surface and Coatings Technology, 1999, 120-121: 44-52. [14] KOIVULUOTO H, VUORISTO P, NAKKI J. Structure and corrosion behavior of cold-sprayed tantalum coatings[C......
particles synthesized by decomposition of aluminium ammonium sulphate [NH4Al(SO4)2] powder in molten aluminium alloy. They showed that 0.8 wt.% of in-situ γ-Al2O3 formed by decomposition of NH4Al(SO4)2......
property prediction system for hot rolled IF steel [J]. Ironmaking Steelmaking, 2014, 41(8): 618-627. [4] ZHOU P, YUAN M, WANG H, CHAI T. Data-driven dynamic modeling for prediction of molten iron......

in the solidification process of castings: liquid, two-phase zone and solid. When the casting is in the molten state, the temperature field has no effect on the distribution of the force field. When the casting......
dissolved in the molten ferrous material. As a result, it shows finer homogeneous dendrite shape over the surface modified region. The laser modified surface improved their hardness up to HV0.3 1200. 2......
