. The reduction leads to the improvement of the corrosion resistance after extrusion which is then comparable with the commercial alloy AZ91D. Key words: magnesium-tin alloys; microstructure; corrosion...; 1 Introduction Magnesium alloys exhibit attractive property......
Production, Properties and Applications of Bulk Amorphous Alloys Akihisa Inoue1,Tao ZHANG1 (1.Institute for Materials Research, Tohoku University, Sendai 980-8577, Japan) 摘要:A review is given of recent work concerned with the production method, the characteristic properties(1) Bulk amorphous system; (2) Mechanical and magnetic properties of bulkamorphous alloys; (3)application of bulk......
and microstructure control have always been taken as efficacious measures in gaining further improvement of the performance of alloys[3-4]. The function and effects of lithium in aluminum alloys have been studied for long time, and 8000 series of aluminum-lithium alloys have been developed and applied in the aerospace industry because of their light mass, high specific strength and high elastic modulus......
Effect of Lanthanum and Yttrium on Microstructures of Cu-Cr alloys Zhang Meng1,Liu Guoming1,Shuai Gewang1,Yin Jianying1,Chen Xiaofang1 (1.School of Materials Science and Engineering, Nanchang University, Nanchang, Jiangxi, 330047, China) 摘要:Microstructures of Cu-based alloys (including Cu0.8Cr0.05La, Cu0.8Cr0.1La, Cu0.8Cr0.4La, Cu0.8Cr0.05Y,Cu0.8Cr0.1Y and Cu0.8Cr0.4Y) were studied by optical......

) and differential scanning calorimetry (DSC) were employed to investigate the influence of Ni content on the crystallization of amorphous Zr70,Cu30-xNi, (atom fraction in %) alloys. Experimental results show that with the Ni content increasing the activation energies for crystallization of amorphous Zr70Cu30-xNix alloys increase correspondingly, indicating that the thermal stability is greatly improved. All......
