Microstructure and Performances of Nanocrystalline Zinc-nickel Alloy Coatings LI Guang-yu1,NIU Li-yuan1,JIANG Zhong-hao1,LIAN Jian-she1 (1.The Key Lab of Automobile Materials, Ministry of Education, China, College of Materials Science and Engineering, Jilin University, Nanling Campus, Changchun, 130025, China) 摘要:Nanocrystalline zinc-nickel alloy coatings were deposited from an alkaline......
Amorphous in a Zr-IQC-DQC pseudo-ternary alloy systemPatrick Weisbecker摘 要:<正> A pseudo-ternary alloy system was constructed by combining an icosahedral quasicrystal (IQC), a decagonal quasicrystal (DQC), and Zr into one alloy system. Different proportions of Zr were added to pseudo-binary alloy IQC80DQC20 (mass fraction in %). Structural......
Trans. Nonferrous Met. Soc. China 22(2012) s656-s660 Microforming of superplastic 5083 aluminum alloy Md. Abu Mowazzem HOSSAIN1, Sung-Tae HONG1, Kyu-Yeol PARK1, Young-Sang NA2 1. School of Mechanical...: The mechanical behavior of superplastic 5083 aluminum alloy during microforming process was investigated by finite element analysis. A micro V-groove die was modeled to analyze the effects of forming......

="ChDivSummary" name="ChDivSummary">A study was conducted to examine the isothermal oxidation behavior of a new Ni-Cr-W-Al alloy in air at 1250℃ with different time. Oxidation kinetics was determined from weight... of the alloy were a compact and continuous outer Cr2O3 and NiCr2O4 layer and an inner Al2O3 layer that was in dendrite shape. Oxides scales with good adherence were formed on the surface of the alloy......
