corrosion resistance and adhesion to epoxy resin paints.It was found out that the hybrid films could efficiently be a substitute for chromate based primer over aluminium alloy.关键词:... University,Shenyang 110819,China摘 要:Three titanium-zirconium-phosphonate hybrid films were formed on AA6061 aluminum alloy by immersing in fluorotitanic......
solidified NiAl-Cr(Mo) near eutectic alloy and developed a series of high-temperature strength alloys, while the Hf addition decreased the ductility evidently at the same time. NiAl-based composites... of a nickel 36at.% aluminium alloy [J]. Met Sci J, 1972, 6: 20-24. [28] MISRA A, GIBALA R, NOEBE R D. Deformation and fracture behavior of a directionally solidified beta/gamma Ni-30at.pct Al alloy [J......
of multilevel series rules, multilevel parallel rules and multilevel series & parallel rules were established. The correlation coefficients (R) are 0.992, 0.988 and 0.990, respectively, and the average absolute relative errors (AAREs) are 6.77%, 8.70% and 7.63%, respectively, which proves that the constitutive equations of multilevel series rules can predict the flow stress of pure aluminum......
used alloy in the 7xxx series with superior properties comparable to soft steel. Aluminium alloys are generally fabricated with casting and forging processes [1-6]. The formation of defects... trace formation in the solid grains. Key words: semi-solid alloy; cooling slope casting; thixoforging; AA7075 alloy 1 Introduction Aluminium alloys possess remarkable engineering properties like low......
