And the variation of oxide shell thickness was calculated at the same time. The particle size, morphology and composition of the atomized micron aluminum-magnesium alloy powder were tested by the laser particle size analyzer, the scanning electron microscope, the energy dispersive spectrometer and the X-ray transmission scanning. The gas volumetric method was used to measure the activity of the alloy powder after the thermal oxidation test. The results show that the activities of the atomized micron Al-Mg alloy powder decreased with the increase of particle size and decreased with the increase of Al-Mg-Al alloy ratio at 71℃. The activities of the Al-Mg alloy powder remained almost stable after 24 hours of oxidation. | 查看全文查看/发表评论下载PDF阅读器 | |
