National Engineering Research Center... master alloy on the grain size of LA141 alloy was investigated as well as the effects of the total reduction of cold rolling and the annealing temperature on microstructure, mechanical properties......
grain sizes were fabricated under the same condition by not adding or adding different amounts of saccharin (0.55, 0.65, 1.00 g/L) into the electrolyte. Crystallographic structure of the Ni deposits... Effect of grain size on corrosion behavior of electrodeposited bulk nanocrystalline Ni QIN Li-yuan(秦丽元), LIAN Jian-she(连建设), JIANG Qing(蒋 青) Key Laboratory of Automobile Materials of Ministry......
deformed magnesium alloys with initial grain structure obtained by continuous dynamic recrystallization (CDRX) is controlled by a process of grain coarsening without the evolution of the preferred... by mechanical polishing using diamond solution with particle sizes ranging from 1 to 3 ?m. Revealing of the grain structure was achieved by subsequent etching in a solution of acetic picral at room......
an obvious refinement effect on the cast grain of magnesium and its alloys without the alloy element Al because the crystal structure of zirconium is the same as magnesium matrix, and the lattice...]. For example, rapid cooling and stirring of the solidifying melt effectively refine the grain structure in some high-pressure die casting processing. Superheating of the magnesium alloy melt, which......
in the casting, which otherwise solidifies with coarse columnar grain structure[2-3]. A fine equiaxed grain structure leads to several benefits, such as high yield strength, high toughness, improved... transition from columnar to equiaxed structure in Fig.3. This difference in grain refining efficiency could be attributed to the size, morphology and distribution of Al3Ti particles presented in the master......
