Relationship between heat treatment and corrosion behaviour of Mg-3.0%Nd-0.4%Zr magnesium alloy CHANG Jian-wei(常建卫), GUO Xing-wu(郭兴伍), FU Peng-huai(付彭怀), PENG Li-ming(彭立明), DING Wen-jiang(丁文江... in the following order: T4>T6>F. To date, there is no detailed study on the effect of heat treatment on corrosion behaviour of Mg-Nd-Zr ternary alloy. In this work, the relationship between heat......
Trans. Nonferrous Met. Soc. China 22(2012) 1582-1587 High temperature oxidation behavior of directionally solidified NiAl-31Cr-2.9Mo-0.1Hf-0.05Ho eutectic alloy WANG Zhen-sheng1,2, XIE Yi2,3, GUO... 2012 Abstract: The isothermal oxidation behavior of NiAl-31Cr-2.9Mo-0.1Hf-0.05Ho directional eutectic alloy was investigated with the help of scanning electron microscopy and X-ray diffraction......
and initial orientation of SRX grains during the isothermal annealing were investigated. The results show that SRX can be accelerated through high-density twins introduced by high cumulative strain... gradually in the final stage at low cumulative strain. The relationship between recrystallization volume fraction and annealing time can be perfectly described by JMAK equation at high cumulative strain......
μm at atmospheric pressure to 10 μm at 6 GPa gradually. Also, Mg(Zn,Cu)2 and MgZnCu eutectic phases were distributed in the shape of network, while under high pressures the second phases (Mg(Zn,Cu)2... are the principal strengthening mechanisms. Key words: high pressure solidification; Mg-Zn-Cu-Zr alloy; strengthening mechanism; eutectic transformation 1 Introduction Up to now, Mg-Zn-Cu alloy has been......
and α2 phases with the (111)γ//(0001)α2 relationship, and the orientation of which is determined by the primary phase. When α phase is formed as the primary phase, the lamellar structure usually has.... The volume fraction of B2 phase increases with the increase of the growth rate. 4) The α2/γ lamellar only lies parallel and 45 ° to the growth direction by the Burgers orientation relationship under......
J. Cent. South Univ. (2016) 23: 1508-1514 DOI: 10.1007/s11771-016-3202-1 Improved SMB speckle filtering of polarimetric SAR data with synergistic use of orientation angle compensation and spatial... deficiencies. First, the orientation angle compensation is incorporated into the SMB filtering process to remedy the overestimation of the volume scattering contribution in the Freeman-Durden decomposition......
